It's amazing how lazy the supply siders are on this argument. Of course there's no good data-- real estate interests fight to prevent that data from even being collected. You only have to drive around major cities at dusk and see how many units have no lights on for weeks on end to recognize the magnitude of the problem. There may be data from Vancouver BC and other places that have passed vacancy taxes to address the issue. Further, the amount of construction resources that go into building luxury condos and other useless units are resources that CANNOT be used to build good housing. There is a limited supply of labor and supplies for that.
