And again, how is keeping those areas run-down going to
1) help keep blight from destroying the neighborhood completely (i.e. Baltimore), and
2) encourage "minorities" not to self-segregate?
By increasing property values, many original residents can’t afford the increased taxes and are forced out of the area.
And when that happens you have a lot of political people screaming about whites (or rich) moving into historically non white (or poor, I have seen this play out in non racial ways) areas, and how that is wrong.
Some times developers use the increased property taxes as a way to scoop up more land.
