Must-Read: Derek Thompson: How American Cities Can Make America Great Again: “Even if the federal government were a monarchy…

…some of the most significant policy decisions happen at the local and state level, where federal power holds little sway. The president cannot force richer cities to raise their minimum wages above the national minimum, nor can the executive branch alone force states to spend more money on poor neighborhoods’ public schools. But perhaps the best example is America’s housing policy. As much as tax policy or defense spending can shape the economic fortunes of families and generations, people are not just products of the District’s mandates. They are also products of local geography—which is determined city by city, and block by block….

Several major cities have missed out almost entirely from the recovery. In Detroit, Memphis, and Toledo, the number of businesses declined between 2010 and 2013. In Cleveland and Cincinnati, total employment shrunk as well. In other cities… the recovery has been so frothy that the housing market is back to its pre-crash highs…. Austin, Buffalo, Denver, Honolulu, Nashville, Pittsburgh, [and] San Francisco. In three other metros, prices are within 5 percent of their all-time highs: Durham-Chapel Hill, Houston, [and] San Jose…. The return of record-high home prices in metros rich with new college grads is both an achievement and a warning. It’s an achievement, because there is a strong relationship between long-term growth and cities that assemble smart people…. But it’s a warning, too, because long-term growth requires that those people can afford to stay in the city….

There are some good reasons why expensive cities tend to be on the water. It’s hard to builds apartments on the ocean. But restrictive housing policies—for example, height restrictions and rules prohibiting the construction of new homes or multifamily housing— are a man-made tax on agglomeration, pricing smart people out of places they want to live and the places where they could best work. This, in turn, deprives some cities of the very job multiplier that Moretti hailed…. This isn’t a concern on the level of a city, but of the nation as a whole…

…every individual measure of human interaction there also increases by 15% to 20%. Not so long ago, futurists predicted that the ease of electronic connectivity would make big cities obsolete. Instead, Harvard University economist Edward Glaeser and others now say that improvements in information technology strengthen cities that are centers of innovation by speeding the flow of ideas. Urban density facilitates contact between smart people and fosters innovation, increasing urban incomes as new businesses take hold, they say…. To my taste, to have high density be delightful, there are five key desiderata: 1. plenty of floor space in the home. 2. no stairs within an individual family’s home…. 3. plenty of windows looking out. 4. excellent soundproofing. 5. plenty of green space nearby All of these are compatible with very high density, given good design….

Even as things are now, I think Manhattan is very pleasant. With residential buildings like the ones I am describing, almost any city could have high density and be even more pleasant than Manhattan is now–except for one thing: as long as each family gets plenty of floor space, no stairs to climb, plenty of windows, excellent soundproofing, and plenty of green space, when it comes to cities, bigger is better. And New York City has a head start.
