Affirmative Action / Poverty / Oppression / Blame

So a neighbourhood is a nice place, then some black people move in. The white people move out, it all turns to garbage and... it's not the fault of those that remain?

I'm not sure where you're trying to go with this point.

(at least I saved some of your post)

It's not the fault of those that remain. It is their fault that they do remain however. Although we did get Harlem from this nice process.
