And you're wrong, Al, 'slum clearance' doesn't make a place not a ghetto.
You think that the slum dweller makes the slum then? No, those who victimize the slum dweller make the slum. They don't stop victimizing him just because he has a new hovel.
Decent houses = more power (in various different ways) to the people that live in them. Obviously that wouldn't be a solution to the complicated trap that most blacks are caught in, but it'd be a big improvement in quite a few ways. Though, obviously, there's no chance of it happening any time in the next few decades for the usual reasons...
Don't get me wrong, I think they should be given new houses, of course. But I think we also need to take away the 'houses' - the powerful positon - of those who are victimizing them in the first place.
