Paul Krugman: Inequality and the City

We’re not just talking about the superrich here, or even the 1 percent. At a guess, we might be talking about the top 10 percent. And for these people, it’s a happy story. But what about all the people, surely a large majority, who are being priced out of America’s urban revival? It would be interesting to see how much housing would have to be added to NYC generally (and Manhattan particularly). Rising demand for urban living by the elite could be met largely by increasing supply. There’s still room to build, even in New York, especially upward. Yet while there is something of a building boom in the city, it’s far smaller than the soaring prices warrant, mainly because land use restrictions are in the way.
