millions of Americans living in trailer parks set up by the government
Oh, but that's worked so well in New Orleans....
The Grapes of Wrath model is wrong. In that period, the land owners wanted people off their 20 acres so that they could consolidate the land into larger farms where machinery made for higher productivity. Sorta like the Scottish highland clearances. These bubble markets are in cities. There's no upside in simply leaving housing empty vs. renting it. Ownership may change but that's about it.
