When the rich and the poor compete for housing on the open market, the poor don’t stand a chance. The rich can always outbid them, buy up their tenements or trailer parks, and replace them with condos, McMansions, golf courses, or whatever they like. Since the rich have become more numerous, thanks largely to rising stock prices and executive salaries, the poor have necessarily been forced into housing that is more expensive, more dilapidated, or more distant from their places of work.
