> Creating more housing doesn't "fix" the problem, because the more wealthy buy two or more houses, and are happy to leave one empty This surely can't go on forever though. People's ability and desire to consume housing is not infinite, particular in a given locale. If they're buying them to rent out, then a flood of other wealthy people looking for tenants reduces the landlords' bargaining power in the market, which means rents have to drop eventually. If this isn't happening yet, it's most likely because the amount of housing being produced is still too small. You can't purely demand-side subsidy your way out of housing being expensive. You have to build.
