I think a big part of the problem is that many of those uninhabited places are so nice. Only the wealthy can afford to keep property vacant. And there’s just such disgust at the idea that the homeless, of all people, could be allowed to live in ritzy places that they didn’t “earn.” I think of that scene in Dr. Zhivago when the aristocratic family comes home and finds their Moscow palace taken over by dirty working families—dozens of people living in a place once left nearly empty. But the scene is supposed to be disgusting.
