Illegal Immigrants Didn’t Break the Housing Market; Bad Policy Did

From Alex Tabarrok.

"In an interview, JD Vance claimed:

[H]ousing is way too expensive….because we flooded the country with 30 million illegal immigrants who were taking houses that ought by right go to American citizens.

I noted on Twitter that this framing reeks of socialist thinking, national socialist to be precise. A demand for the state to designate a privileged class that get special rights to scarce goods. Treating housing as a fixed stock to be allocated to a favored in-group while blaming an out-group for shortages is collectivist politics driven by grievance, not market reasoning. In short, grievance and entitlement, zero-sum thinking and central planning wrapped into one ugly bundle.

That criticism set people off. The first rebuttal was predictable “Ha ha, the economist forgot about supply and demand!”—a miss, because my point wasn’t about the mechanics of house-price growth but about Vance’s rhetoric: the collectivism and the cheap politics of blaming outsiders. The second rebuttal was that “America belongs to Americans” so of course illegal immigrants shouldn’t be allowed to buy homes.

The second objection is amusing because who is harmed most when a government bans immigrants from buying homes or deports a chunk of potential buyers? American home sellers. The way such bans “work” is by preventing sellers from accepting the highest bid. In effect, these policies are a tax on sellers combined with a subsidy to a subset of buyers.

So bans on foreign buyers are really about taxing some Americans and subsidizing others. Moreover, although the economic logic of illegals pushing up demand is sound, the numbers don’t add up to much. First, there aren’t 30 million illegals; the best estimates are roughly 14 million. And second illegals are obviously not the reason homes blow past a million dollars in places like San Francisco, San Jose, Washington, or New York! The effect of illegal immigrant on house prices exists but is small—the bigger factors are native population growth, rising incomes, zoning rules, and strict limits on new construction. Block illegal immigrants from buying homes and you will get a pause in price growth, but once demand from natives keeps rising against a capped supply, prices will climb back to where they were.

That gets to the deeper problem with Vance’s style of thinking. If “fixing” housing scarcity means blaming whichever group is politically convenient, you end up cycling through targets: illegal immigrants first, then legal immigrants (as Canada has done), then the children of immigrants, then wealthy buyers, then racial or religious minorities. Indeed, one wonders if the blame is the goal.

If you actually want to solve the problem of housing scarcity, stop the scapegoating and start supporting the disliked people who are actually working to reduce scarcity: the developers. Loosen zoning and cut the rules that choke what can be built. Redirect political energy away from trying to demolish imagined enemies and instead build, baby, build."
