U.S. income inequality trends in the 21st century

Two shoppers make change for a purchase in New York.

How much has income inequality risen in the United States? Well, how do you define income? And what time period are you looking at? The most well-known statistics about income inequality—including the famous data from economists Thomas Piketty at the Paris School of Economics and Emmanuel Saez at the University of California, Berkeley—are based on tax data and show a significant increase in inequality since the late 1970s. But are the trends revealed in those data over that time period still holding up? Digging into the data reveals that inequality trends since 2000 actually are different from those during the 1980s and 1990s.

A paper released last week as a National Bureau of Economics Research paper takes a look at how income inequality has changed in the 21st century. The two authors, Fatih Guvenen of the University of Minnesota and Greg Kaplan of the University of Chicago, take a look at two different sources of income data. The first is administrative tax data that cover all forms of income, and the second source is data from the Social Security Administration based on W-2 forms, which only cover labor income. In other words, the tax data capture both labor and capital income, while the SSA data pull in labor income alone.

The two datasets show broadly the same trend in top-end income inequality from the early 1980s to the late 1990s. The one exception is the period of 1986 to 1988, when the tax data show a jump in inequality, which Guvenen and Kaplan point out is probably due to tax reform in 1986. But for the most part, the data agree that inequality rose from the late 1970s to the beginning of this century.

But around the year 2000, the data show something different. The tax data continue to show an increase in income inequality, but the SSA data indicate a negligible or no increase at all. The authors explain that they first examined whether the two data series were showing different trends because they used different units of measurement (tax filers for the tax data and individuals for the SSA data). But that doesn’t seem to be a big contributor. Rather, the difference seems to be the kind of income the data are capturing.

Income inequality since 2000 is not a story of rising inequality of labor income, but an increase due to higher capital income. Specifically, the rise is due to increased business income from S-corporations. The rise of pass-through businesses such as partnerships has been the primary source of rising inequality in the 21st century. Guvenen and Kaplan also show that the increase in income inequality hasn’t been primarily a story of the top 1 percent of income earners, but rather the top 0.01 percent. This makes sense, as ownership of pass-through entities is far more concentrated than the high labor incomes that fueled the increases in inequality in the 1980s and 1990s.

The increasing importance of capital income over labor income has been noticeable in the Piketty and Saez data, as J.W. Mason of John Jay College pointed out two years ago. The timing is also interesting given that 2000 is when the labor share of income in the United States started to decline.

As the authors of this new paper argue, we need to be careful with describing the trends and facts about inequality. The data about the rise during the two decades prior to the turn of the century, which shows a leading role for high labor incomes, led to diagnoses and solutions focused on “supermanagers” and other kinds of “superstar” workers in the top 1 percent. That line of thinking doesn’t make sense when rising inequality is instead a story of rising capital income among business owners in the top one-hundredth of the top 1 percent. To paraphrase a quote often attributed to John Maynard Keynes, when the facts on inequality change, we should change our thinking about it.

Short thread on what #Brexit is about and why it’s going badly. Historically the Leave leadership took 2 items as articles of faith. They believed: a) Germany runs the EU & German car makers run Germany; b) The EU & Eurozone are sick & are going to collapse any day now. As such, although they may bluster, behind closed doors the EU would be desperate for a free trade deal with the UK. You can pretty much dispense with everything else said by Leave as noise. These are the 2 sacred beliefs at the heart of Leave…

Shaken and Stirred: Weekend Reading: Hoisted from 2005

Stephen Cohen and Brad DeLong (2005): Shaken and Stirred https://www.theatlantic.com/magazine/archive/2005/01/shaken-and-stirred/303666/: The United States is about to experience economic upheaval on a scale unseen for generations. Will social harmony be a casualty?

It has become conventional wisdom that class politics has no legs in the United States today—and for good reason. Regardless of actual circumstance, an overwhelming majority of Americans view themselves as middle-class. Very few have any bone to pick with the rich, perhaps because most believe they will become rich—or at least richer—someday. To be sure, the issues of jobs and wages inevitably make their way into our political campaigns—to a greater or lesser extent depending on where we are in the business cycle. But they seldom divide us as much as simply circle in and out of our political life. Lately anxiety about the economy has been palpable, but for the most part it has not evolved into anger or found specific scapegoats.

Economic insecurity could well divide us in the future, however.

We are on the cusp of an economic era whose challenges will be unfamiliar to most Americans of working age. It is likely to erode the psychological pillars on which class unity has rested in this country: personal economic stability for the middle class, and the promise of at least some upward mobility for most Americans. The most likely division—besides that between the truly rich and the truly poor—will be between those in the middle class who are able (through agility or luck) to manage economic risk and those who find themselves helpless before the economic pressures of a new age.

Once upon a time, or so it is said, America was a place with lots of upward but little downward mobility. In the really old, pre—Civil War days you could start out splitting rails, head west, make a success of yourself on the frontier, and perhaps even wind up as president. In the relatively recent, post—World War II expansion you could do well by landing a blue-collar job in a unionized manufacturing industry or a white-collar job at a large, stable American corporation such as IBM, AT&T, or General Electric—which offered job security, high salaries, and long, steady career ladders.

There was always as much mythology as truth to this image of America. Lighting out for the Territory was expensive. Covered wagons did not come cheap. More generally, although many terms could be used to describe economic life in the nineteenth and early twentieth centuries, “stable” and “secure” are not among them.

But there was considerable truth to the image as well, particularly after World War II.

Regardless of education level or family background, many Americans who valued stability and security really did have the chance to grasp it; jobs with “a future”—that is, with steadily rising wages and solid retirement plans—were plentiful. And even for many of those who were fired, the economic risks were fairly low: the unemployment rate for married men during the 1960s averaged 2.7 percent, and finding a new job was a relatively simple matter. During the first decades following World War II, to the astonishment of interviewing sociologists, a majority of Americans began to define themselves as middle-class.

This immediate post—World War II period stands as a reference point in our popular economic history—a gold standard for rapid growth and shared prosperity, albeit among the limited community of white males. It lingers in our national memory, and remains an important source of confidence in the unity of our culture and the awesome power of our economy. But although it engendered our current economic expectations, our sense of “the way things ought to be,” in reality the postwar era was probably an aberration, a confluence of events never before seen in our history and unlikely to be seen again.

Most obviously, it was an era defined by the isolation of America’s continental market from the devastation of World War II. In the early postwar decades foreign competition exerted virtually no pressure on our economy. (In 1965, for example, imports of automobiles and auto parts came to less than $1 billion—about a fortieth of what they are today, after adjusting for inflation.) At the same time, domestic manufacturers benefited from an enormous pent-up demand for mass-produced goods: cars, washing machines, commercial aircraft, refrigerators, lawn mowers, television sets, and so on. New highways gave rise to new suburbs, and to a resulting construction boom.

These economic conditions, along with successful federal efforts to maintain full employment through loose monetary policy, created an environment exceptionally friendly to workers. With little foreign competition on the one hand and a very tight labor market on the other, American firms were willing and able to offer workers strong incentives—such as pensions and first-rate health insurance—in order to attract and retain them. (Generous tax breaks from the federal government encouraged the roll-out of these benefits.)

Meanwhile, the Great Depression had given rise to a system of government programs and policies that came into full force and maturity only after World War II—among them Social Security, unemployment insurance, welfare, and high marginal tax rates. The rise of communism abroad could only have strengthened commitment to workers’ welfare, as a means of demonstrating that the American capitalist system offered a humane alternative.

Thus favorable macroeconomic circumstances, the absence of foreign competition, and a historically unique political dynamic all combined to allow postwar America many of the benefits of social democracy without the costs. The economy did not stagger under the weight of ample benefits and high taxes. Americans—at least white male Americans—did not have to worry about tradeoffs between security and opportunity, because the United States offered both. And it seemed that this was the natural order of things.

In addition, new technologies and consumption patterns were shifting the U.S. economy’s center of gravity from skilled, unionized, mass-production industry—which fashions products from expensive materials and capital-intensive machinery—to services and retailing, where barriers to the entry of competitors are lower, labor costs more significant, and competitive advantage more reliant on squeezing those labor costs.

The nation’s largest private-sector employer today, of course, is not General Motors or Ford but Wal-Mart. Wal-Mart is in many ways a fine company, but its strategic goals and constraints are quite different from those of the manufacturers of the 1960s. Between them the automakers and the UAW offered workers a fairly robust “social contract”: pensions, good health care, high wages, long-term job security.

Wal-Mart makes no such offer.

By the early 1990s the nature of unemployment had changed as well. As Erica Groshen and Simon Potter, of the New York Federal Reserve, point out, temporary layoffs have become less common. Instead companies under constant competitive pressure are more frequently making layoffs permanent—using advances in technology to eliminate some types of jobs altogether.

At the same time, the rising cost of health care and the falling rate of health insurance have left families much more economically vulnerable in the event of a serious accident or illness. Many Americans today are one lost job and one medical emergency away from bankruptcy.

We do not want to overstate how bad things are. Not even white males would be better off in the economy of the 1960s, when median real household incomes were only about two thirds of what they are today, and much of the medical care that we now fear we cannot afford was unavailable at any price. In a sense we’ve merely returned to a more natural economic state, in which jobs are not always secure and progress is not always assured. And we’ve done so while improving the opportunities and lifestyles available to most Americans. So far, in other words, we’ve adapted reasonably well to increased risk and reduced security. But we’re not at the end of economic history—and the history that will be made in the coming decades is likely to be substantially more turbulent than what we’ve seen in recent years.

Although the impact of globalization on American jobs has been overhyped in the past, its impact in the future will be hard to exaggerate. Last spring saw a short political boomlet of worry over the offshoring of white-collar jobs to India, China, and elsewhere. In the next few years these issues will be raised at the political level once again—and loudly.

The basic storyline is simple enough: what formerly could not be imported now can be. A compelling parallel can be drawn to the latter half of the nineteenth century, when the steel-hulled oceangoing steamship and the submarine telegraph cable revolutionized international trade. Companies could now use the telegraph to tell their agents in distant ports what goods to ship; moreover, powerful steamships made it practical to export not only precious goods (such as rare porcelains, spices, and tobacco) but also staple agricultural and manufactured products: grain, hides, meat, wool, furniture, and machines (which would eventually include motor vehicles, computers, and consumer electronics).

First in a great rush, and then at a somewhat more measured pace, industrial and agricultural workers the world over began to lose their jobs to more-efficient foreign competitors. Illinois could grow wheat more cheaply than Prussia could grow rye. Malaysia could grow rubber more cheaply than Brazil. Of course, displaced workers could generally find new jobs, sometimes better ones. And consumers benefited greatly from lower prices. But that did little to dim the spectacle of immediate dislocation. The expansion of international trade ushered in a century-long storm—though many Americans (perhaps owing to the anomalous calm following World War II) seem to remember only the recent gusts that have buffeted our heavy industries.

The transformation taking place today will have just as great an effect on the world economy. The transoceanic fiber-optic cable, the communications satellite, and the Internet are making much white-collar service work as tradable as anything else. Broadband cables and satellites can connect India or China or Bulgaria to the United States instantly, seamlessly—and almost without cost. A huge new swath of American jobs is beginning to become vulnerable to foreign competition.

When the offshoring of services truly hits (and it will stretch out over several decades), it is likely to deliver a much greater shock to the U.S. economy than the offshoring of manufacturing did. There are several reasons for this. First, in the 1970s Americans’ incomes exceeded those of the Japanese by a ratio of about two to one. The ratio of American to Indian incomes today is more than ten to one. Economists will point out that the gains from trade will thereby be that much greater for the U.S. economy as a whole—and they’ll be right. Indeed, more and greater openness will expand opportunities and raise incomes for some Americans, producing many highly visible winners. At the same time, the potential pay cuts for workers who lose out in rich countries will also be that much greater.

Second, the coming global trade in services will potentially affect a much larger proportion of the U.S. labor force. Even at its height manufacturing constituted only 28 percent of all non-farm employment, and large sectors of manufacturing (food processing, for example) are closely tied to sources of supply and thus immovable. Service jobs constitute 83 percent of non-farm employment in the U.S. economy today, and every job that is (or could be) defined largely by the use of computers and telephones will be vulnerable.

Third, the impact of foreign competition will be borne much more directly by American workers than by their employers. In the 1970s and 1980s foreign imports threatened U.S. companies and workers equally. The CEOs at GM and Ford were on the same “side” as the men and women who worked on the factory floor. The coming wave of economic dislocation will look very different: it will be something that American CEOs do to their own workers.

Not that they’ll necessarily have much choice; offshoring will in many cases be necessary if American businesses are to remain competitive. Remember H. Ross Perot’s “giant sucking sound”? In the early 1990s no one spoke out more strongly against the prospect of job loss caused by foreign competition. Yet on February 7 of last year the Times of India reported that Perot Systems was going to double its employment in Asia from 3,500 to 7,000—nearly half its total worldwide employment. If the economic logic of foreign outsourcing is so overwhelming that Ross Perot can’t resist it, what American CEO will be able to?

None of this is to say that we face a future of permanent widespread unemployment. It is a truth universally acknowledged (except in campaign seasons) that the rate of employment in the United States is set not by levels of imports and exports but, primarily, by whether the Federal Reserve’s monetary policy manages to settle aggregate demand in that sweet spot where neither unemployment nor inflation is too high.

Moreover, during the course of any single year or business cycle the effects of globalization on the U.S. labor market are small. Forrester Research has estimated that by 2018 some 3.3 million jobs in business processes are likely to go offshore. That’s a little more than 18,000 a month—not a huge number in an economy of 140 million jobs.

But—and this is a very big “but”—even though imports and offshoring do not determine the number of U.S. jobs over time, they do powerfully influence the long-run level and distribution of real wages. Eventually the offshoring of service jobs will exert a strong downward pressure on wages and benefits in jobs that stay onshore, just as the offshoring of manufacturing jobs did in the 1980s. Essentially, the pool of workers competing for many service jobs will be increased by, say, several million English-speaking college graduates in India, who will work for a tenth to a fifth of a typical American salary.

In many cases the jobs in question are held by Americans unaccustomed to layoffs or reduced incomes. Often they are high-paying white-collar jobs. The people who hold them may believe that they are on top because they deserve to be: they are smart and industrious; they worked hard in school while others screwed around; they have been diligent and successful in their careers. These people are likely to become very angry when unexpectedly threatened by substantial downward mobility.

How will the country respond when a broad new array of classes and professions are exposed to downward mobility—particularly as others benefit from new opportunities? Will existing class fissures be exacerbated? What new ones might be created?

Winners and losers are unlikely to sort cleanly. People of similar background and training may see their fortunes diverge greatly depending on subspecialty, or on the presence or absence of some idiosyncratic ability that is hard to replicate. But one can make a few predictions. First, the new environment is likely to pit those who are most flexible—most able to shift jobs or careers, most able to absorb unexpected blows, best positioned to benefit from unforeseen opportunities—against those who are less so. The contours of such a divide seem predictable: young versus old, generalist versus specialist, people with savings versus those who depend on their next paycheck.

A second (and overlapping) split might open between those who are highly educated and possess complex skills and those who are merely well educated and skilled. An MIT education may still be hard to imitate abroad. Can the same be said of a finance degree from a state college?

Third, a divide may occur between those—whatever their education or income level—who by disposition can tolerate unexpected income swings across a lifetime and those who abhor uncertainty.

The last group is probably large. The dissatisfaction resulting from falling wages is usually greater than the satisfaction resulting from rising wages. People are not wrong to be risk-averse; for middle-class Americans, just as for portfolio managers, life consists largely of trying to manage risk. This, the Yale political scientist Jacob Hacker thinks, is the source of middle-class Americans’ unease with the current state of the economy—perhaps the primordial form of a sharper discontent to come. “Voters say the economy isn’t getting better because, as far as they’re concerned, it’s not,” Hacker writes. “And perhaps the best explanation for this perception is that Americans are facing rising economic insecurity even as basic economic statistics improve.”

The median annual household income twenty years ago was about $38,000 in today’s dollars. Today it is about $43,000—13 percent higher. Yet, at least in Hacker’s analysis, Americans typically feel that increasing risk and rising inequality have hurt them at least as much as increasing income has helped. Yes, if they are middle-class, they have higher real incomes and living standards than their parents; but the incomes are known to be insecure, and the prosperity is felt to be fragile.

From one viewpoint, economic risk is the flip side of flexibility, entrepreneurship, and innovation—the very things America does best. In the 1980s, when Americans worried about whether the social organization in Japan’s export-manufacturing sector (morning calisthenics, the company song, consensus, lifetime employment, and so on) might offer a better way of doing business, The Atlantic’s national correspondent James Fallows answered with a resounding no. What Americans needed, he argued, was to become “more like us” (the title of his book on the subject), not more like them: America’s competitive advantage was rooted in disorder, constant change, flexibility, mobility, and entrepreneurial zeal.

In 1991 Robert Reich, about to become Bill Clinton’s first secretary of labor, looked at the tremendous expansion of manufacturing and other export-related employment elsewhere in the world and came to a similar conclusion. How, he wondered in his book The Work of Nations, could Americans preserve and accelerate economic growth if the market position and efficiency advantages of America’s largest firms came under threat? He, too, concluded that we needed to shift our focus away from old-style stable mass-production employment to high-knowledge, high-tech, high-entrepreneurship fields. Workers, he argued, should expect to go back to school to learn new skills for new industries.

But embracing change and uncertainty in this way does not come naturally, in the United States or anywhere else, and the pollsters and media-affairs people of the Clinton administration soon told Robert Reich to be quiet: people did not like to hear their government telling them that their jobs were going to vanish.

Economists rightly say that the rising wave of trade-driven service globalization will, like the last waves of trade-driven manufacturing globalization, benefit Americans and foreigners alike. At home more will be won than lost. Fears that expanding trade will destroy jobs and disrupt the economy also need to be counterbalanced by the knowledge that reducing trade—or even failing to expand it—would reduce national wealth potential, destroy future jobs, and ultimately disrupt the economy even more. The social problems of a stagnant economy are far greater than those of a dynamic one.

But economists too readily dismiss concerns about those who lose out, saying merely that they can be compensated. In practice they seldom are. The United States simply does not make the investments needed to turn economic change into a win-win process—investments in retraining and rebuilding that would transfer some of the gains from the winners to the losers (who’ve done nothing personally to merit their loss). In the late 1970s and the 1980s little money was spent on Flint and Detroit in particular, and Michigan in general, to cushion the economic impact as Toyotas and Hondas came to America’s shores. Producers in Japan and car buyers in Boston and San Francisco pocketed the gains, while producers in the Midwest absorbed the losses. As the Princeton economist and New York Times columnist Paul Krugman puts it, free trade is a salable policy only if accompanied by a well-built social safety net and confidence in full employment. But our safety net is full of holes.

Some companies have traditionally provided many of our social services, particularly in the form of health insurance and retirement support. Those companies will not continue to sustain that burden in the future. At the same time, our limited system of government benefits will not be adequate to the changes that we’ll face—leaving aside the possibility that it may be weakened or removed completely, as some politicians propose. That system was designed to protect the poor and the aged, and to tide the rest of us over in case of (temporary) job loss. What we need now is far more career-transition assistance for the middle class, and perhaps more government funding and (surely) portability for the benefits—notably health care—that the private sector increasingly fails to provide. America’s economy will need flexibility in order to compete, but we can provide this protection without sacrificing our flexibility.

Because we are facing an economic transformation that will hit not over the course of a few years but over the course of the next generation, we have time to do what needs to be done. We will need all this time, because the approaching economic shock will be greater in magnitude than anything in recent historical memory.

Should-Read: Simon Wren-Lewis: Henry Farrell on economists and austerity

…To quote:

If we had responded to the 2007-08 financial crisis the same way we did to the 1929-32 financial crisis, we’d still be waiting for a rerun of World War II to pull us back to normal.

I get very annoyed when people ask me what economists have done to deserve respect over the last decade. We avoided another Great Depression, that’s all. It may have been politicians top priority, but we told them what needed to be done, as Farrell makes clear.

But when Farrell suggests that austerity could have been avoided if only economists had stayed united, I think he is wrong. If you view 2016 as an experiment to see if policy can really ignore the united view of academic economists, the result is that it can. While it is important to hammer home what a mistake austerity was, and that it was never the policy recommendation of the majority of economists, the key question is why on occasion that often overwhelming majority can be so easily ignored on issues economists know more about than anyone else….

…Both inside and outside the Communist world, Marxism succeeded in securing a near monopoly of the critique of liberal theory and practice…. Like other faiths, Marxism operated in a circle of ideas, which contained simple but powerful devices for counteracting the effect of any hostile ideas and evidence…. Self-maintaining circles of ideas of this kind are astonishingly effective and robust. The fact that some segments of the circle carry an amazing load of blatant falsehood fails to subvert the circle as a whole, always provided that two conditions are satisfied: that the circle holds firm internally and does not itself deny any of its own elements, and that it also contains important segments which record great insights and have a genuine appeal and which thus provide deep psychic satisfaction for the adherents….

What in fact happened to the Marxist Circle? Twice it was crucially breached from the inside… by Khrushchev… by Gorbachev. The first time… the wound was not all that deep…. The second, Gorbachevian liberalization…. Suddenly it became plain that no one subscribed to the faith anymore…. Under Brezhnev, it quietly ceased to be an Umma: it had entered this period still endowed with faith and left it wholly devoid of it.

Theoretically, it now faces three alternatives: it could return to both authoritarian centralism and to faith and become an Umma once again… it could continue in its faithless way while retaining a centralized… single hierarchy… it can reacquire civil society-in other words, a set of institutions strong enough to check the state, yet not, so to speak, mandatory enough from the viewpoint of individuals to constitute an alternative form of oppression….

Weekend reading: “This post has intangible assets” edition

This is a weekly post we publish on Fridays with links to articles that touch on economic inequality and growth. The first section is a round-up of what Equitable Growth published this week and the second is the work we’re highlighting from elsewhere. We won’t be the first to share these articles, but we hope by taking a look back at the whole week, we can put them in context.

Equitable Growth round-up

Corporate profit-shifting is a problem for a source-based U.S. corporate tax system, but it’s also a problem for the measurement of gross domestic product. A new paper shows how increased profit-shifting has caused us to underestimate U.S. productivity growth.

In a paper released this week as part of the Equitable Growth working paper series, Owen Zidar of the University of Chicago finds that “the positive relationship between tax cuts and employment growth is largely driven by tax cuts for lower-income groups.”

Data on labor market flows (hiring, firing, and quitting) from the Job Openings and Labor Turnover Survey for the month of February were released this week. Check out three key graphs from the new data.

Economists are increasingly drawing attention to the influence that firms have on levels of income inequality. A new paper shows that not only do firms decide which rungs workers start on a wage ladder, but also how fast they move up the income ladder.

Notes: Working, Earning, and Learning In the Age of Intelligent Machines

The key seems to me to build intelligent machines that will assist workers in labor-intensive industries, rather than build intelligent machines that will eliminate workers in capital-intensive industries. The first is a clear win. The second can be a major loss if the things made in capital-intensive industries are close enough substitutes for the products of labor-intensive industries to greatly drop their value.

But what I have to say so far is limited.

It is simply made up of: Five Disconnected Points:

  1. Cast your mind back to 1999. All of this was then viewed not as a threat but as an opportunity. Few things can turn a perceived threat into a graspable opportunity like a high-pressure economy with a tight job market and rising wages. Few things can turn a real opportunity into a phantom threat like a low-pressure economy, where jobs are scarce and wage stagnant because of the failure of macro economic policy.

  2. Those historical cases in which technological progress has been genuinely immiserizing have been relatively few. They have been confined to situations in which technological progress takes the form of greatly amplifying labor productivity in capital-intensive occupations. Those then shed labor massively, as those tasks in which human beings act like robots—filling in the gaps that machines cannot yet do—vanish. But at the same time technological progress must do next to nothing to equip workers in labor-intensive occupations with better tools to assist them. Thus the canonical case is the 19th century handloom weaving industry in Britain and India. That suggests a focus on building robots to serve as tools and assistants for workers in labor-intensive industries, as opposed to further mechanizing and thus replacing workers in capital-intensive industries.

  3. Let me endorse the observation that for the past 200 years the mechanization of manufacturing has to a great degree involved treating humans as if they were robots. We can do better. At least, we hope we can do better.

  4. Let me try to satisfy Barry’s demand for less abstraction and also endorse Nils’s emphasis on human customization by asking you to cast your minds back to the days of Metropolis, Henry Ford, and Brave New World. Henry Ford wanted to satisfy real human needs in the cheapest and most effective fashion by taking massive, mammoth, and total advantage of all possible economies of scale. You can have a car in any color you want: as long as it is black. You can have whatever kind of car you want: as long as it is a Model T. You can wear any clothes you want: as long as they are identical blue overalls. You can play any sport you want: as long as it is Centrifugal Bumble Puppy. That was not the world people wanted. Alfred P. Sloan and General Motors drank Henry Ford’s milkshake by finding a sweet spot, in which you sold everybody mass produced Chevy parts in different, near personalized configurations. We can argue about whether people should value such human touch salesmanship and customization—whether it is a cognitive behavioral mistake stemming from our origin as hunter gatherers seeking to gather the most useful objects. But the fact is we do value such human touch customization. All the evidence suggests that it makes us very happy. That is a very large set of potential labor-intensive occupation that will last for a very long time.

  5. Never forget that back in the environment of evolutionary adaptation we were sociable toolmaking hunter-gatherers—constantly interacting with the complex environment where we would choose and modify objects to advance our purposes—in which we turned ourselves into an anthology intelligence under a geas to learn as much as possible, and immediately tell it to—gossip about it with—everybody else. With the coming of first the Agrarian and then the Industrial Age our jobs became overwhelming boring. Only humans, with our brains being supercomputers that fit into a bread box and draw only 50 watts of power, could be the necessary microcontrollers for animals and machines necessary for first Agrarian Age and then Industrial Age production. But those jobs vastly underutilized the human brain. Do not overromanticize looking at the hind end of a mule or tightening bolt number six on every object coming down the assembly line for four hours without a break.

…felt compelled to walk, drive or take the T… down to MIT’s Sloan Building… to listen to Kindleberger…. We understood about half of what he said and recognised about a quarter of the historical references and allusions. The experience was intimidating: Paul Krugman… a member of this same group… awarded the Nobel Prize… has written how Kindleberger’s course nearly scared him away from international macroeconomics. Kindleberger’s lectures were surely “full of wisdom”, Krugman notes. But then, “who feels wise in their twenties?” (Krugman 2002).

There was indeed much wisdom in Kindleberger’s lectures, about how markets work, about how they are managed, and especially about how they can go wrong. It is no accident that when Martin Wolf… challenged… Lawrence Summers in 2011 to deny that economists had proven themselves useless… Summers’s response was that, to the contrary, there was a useful economics… of the pioneering 19th century financial journalist Walter Bagehot, the 20th-century bubble theorist Hyman Minsky, and “perhaps more still in Kindleberger” (Wolf and Summers 2011).

Summers was right. We speak from personal experience: for a generation the two of us have been living–very well, thank you–off the rich dividends thrown off by the intellectual capital that we acquired from Charles Kindleberger, earning our pay cheques by teaching our students some small fraction of what Charlie taught us…
