I wonder if some variation on Booker T. Washington's plan wouldn't work better for these kids. . . . instead of an "us versus them" (having the white intellectuals doling out a few spots in a good school and bus a few kids over there), get together a group of no-nonsense, politically incorrect, and highly motivated successful black businessmen to start a program IN their community FOR the community. That would short-circuit the whole self-loathing thing right from the start - "look - I did it, despite all disadvantages, and you can do it too."
Might have to start with a good dose of practical, trades-oriented education side by side with academics, so the first groups of students could get out there and earn good money quickly - nothing like bringing home a fat paycheck to impress the younger kids coming along. (My dad made all us kids learn a trade as well as an academic specialty. I know this may cause some resentment in certain quarters as making students "second class citizens", but what the heck are they now? They don't know a trade, PLUS too many of them can't even read or write on a high school level when they graduate!)
But then the white liberal elitists couldn't revel in the smug self-satisfaction of having "cared".
But, you're quite right, that's what blacks like Booker T. Washington and George Washington Carver and many others did in the post-Civil War era in the South.
