This is a theme on which I regularly opine at Cagle.com. I have to admit much of the fact-based opinion I provide comes from the works of Dr. Sowell who is an American icon and a personal hero. He is horribly maligned by those on the Left who've heard of him and there could be no better way to establish one's bona fides.
Nothing has done more to destroy the black family than the (not so) Great Society initiatives of LBJ. Prior to them, blacks had rates of marriage and legitimacy equivalent with white America. Only armies of workers willing to appeal to "do it for the children" managed to break down the pride of black families to take welfare handouts. Of course, only single mothers get large stipends and the rest is, as they say, history.
