Man, I hope the researchers quoted in that housing article will get up the courage to read The Bell Curve, because it answers a bunch of their questions. Specifically, it uses data to demonstrate that, because poverty is *largely* associated with cognitive abilities, poverty does indeed "accompany" people no matter how much external forces, such as the government, try to change their impoverish circumstances.
As several former housing project residents stated in the article, all the bad stuff just came right with the people into the new neighborhoods.
I also found it interesting that TBC spends quite a lot of time talking about community and valued places in communities for people of all cognitive abilities. So many of the people in the housing article lamented their loss of place in community, having ended up just as poor, with almost as many problems in their neighborhood, but without the sense of community and the ability to find a valued place in it.
