I watched this happen in New York (I'm old enough to say that!). The Democrats systematically destroyed neighborhoods in a process they called "gentrification," thereby running the people who couldn't affprd the new, fashionable condos out (all the stories you've heard about the methods they used to get people out of the buildings are true). But, never fear! They provided "public housing:" crime-ridden, institutionally-painted, occasionally-maintained high-rises. Their residents are completely dependent on government for their most basic needs, roadblocks to their independence having been carefully placed. These places are little more than Democrat vote-farms. Looks like it''s now the national plan.
