Have you read Sowell's "Black Rednecks and White Liberals?" It demonstrates quite persuasively that the main reason some groups stay stuck in poverty isn't racism and social injustice but lack of a culture of responsibility. Really fascinating stuff! I bet you'd like it.
I'll make sure to get it and read it this week. Sowell is awesome.
Have you read John McWhorter's "Losing The Race"?
