When government tries to move people out of the ghettos that government created, a funny thing tends to happen: the people tend to relocate into areas that are similar to the ones they left. That's in part due to the effect of generations of programming; they simply don't know how else to live.
When minority families are given a chance to move out of poor, segregated inner-city neighborhoods, many wind up living in places that look an awful lot like where they started. Or, often, they wind up moving back.
“We say ‘people need choices,’ and that’s absolutely true,” says Stefanie DeLuca, an associate professor of sociology at Johns Hopkins University. “But part of what goes into choices is having had exposure to things that other people have had, to say, ‘now I want this, this is something I can see that’s possible for me.’ Being poor doesn’t just mean you didn’t have enough resources and you had barriers to opportunity – but the benefits of those opportunities are relatively unknown.”
And how could they know, when all they've ever experienced is the kind of environment in which they were raised? How can you expect them to succeed elsewhere, when everybody and everything they've ever known was the government-created ghettos?
Even if you do relocate them from, say, the inner city to the suburbs, they bring their ghetto-oriented behavior patterns with them. As one commenter notes from personal experience: "Putting these people into a nice neighborhood is like putting a cancer cell into a healthy body."
It may seem harsh or judgemental, but it's also fairly accurate: they bring with them the behaviors that they learned in the government ghettos. There's very little that government does well; social engineering is definitely not among them - as they've proven repeatedly over the course of the last half-century.
