Actually, those things did nothing but destroy their sense of self-worth.
Imagine what would constantly be going through your mind if you knew you got the acceptance/job/house just because your skin is...whatever color it is, and not because you werethe best at doing something, or otherwise highly qualified.
I did not grow up in a wealthy family but my mother taught us to have pride. So many speeches, songs about black pride.
In S. Africa...they murdered the white farmers because they felt they deserved the land. Heck if I know what the mindset is...in the beginning it was the schools. Integration never changed things.
Yet why any inner city blacks would not welcome school vouchers is beyond me.
