In his column Monday, the New York Times’ Paul Krugman argued that as members of the top 10 percent of earners — the majority of whom are white — increasingly want to “live near the center of big cities,” these cities aren’t merely becoming more gentrified, they’re also becoming racially and ethnically homogeneous.
The only solution, Krugman asserted, is to build more lower income housing in the inner city, which is something developers are loathe to do. However, “this is an issue over which local goverments have a lot of influence.” A city like New York can’t do much about the influx of the wealthy into the inner city, but it can increase the supply of housing, thereby making sure “the inward migration of the elite doesn’t drive out everyone else.”
