America has a problem: We’ve got too many houses and not enough people with the money or inclination to buy them. So we need one of two things: either fewer houses, or more people who have the means and the desire to buy a house.
As Matt Yglesias points out, "the Census Bureau says the median value of owner occupied housing in the United States is around $185,000." The median value of unoccupied housing is likely lower. If we want immigrants purchasing our $500,000 McMansions, there's no reason we don't want them purchasing our $250,000 townhouses. And once they're here, we want them to work.
Obviously, the politics of this are tough: The American people are ambivalent about immigration and concerned about competition for scarce jobs. But the economics are clear: If we had immigrants with disposable income and skills, that would help create the sort of demand — both for housing and for other goods — that would create jobs. And we wouldn’t have to knock down so many perfectly good homes.
Update: Brian Fallon, spokesman for Sen. Chuck Schumer, e-mails:
True! I tried to nod at this by writing “they have to purchase at least $500,000 in homes to qualify,” but Fallon is right: I should have been clearer. But this just goes, I think, to underscore how inane our immigration policies are. Are we really in a position right now to turn away an immigrant who will create five jobs? Or buy one $270,000 home in an area with a high vacancy rate?
