As a lawyer whose practice is almost solely disability law, mostly for the black poor, I see the evidence all day, every day.  What I do NOT see is that "the contexts in which crime and some other human ills flourish . . . are not neutral or benign in origin, but rather that they have been produced intentionally and systematically by those that have the power to promote advantage for some segments of the population and disadvantage for others."    Do you really believe that within the past 60 or so years "the (white) powers that be" created the "context" --- inner city slums, the black sub-culture moral code, the crime, the poverty -- "intentionally" and "systematically" to promote their own advantage?  Let's assume, wildly, that they did.  Don't you think that that creative act is by now so attenuated, given the power of each of us to create ourselves, that it's downright harmful to the black poor to perpetuate the notion that the culprit is white America?
