Is that the main reason the black community struggles much harder today (proportionally) than it did in the 1950s and 1960s is the total collapse of the nuclear family in many areas. Every reputable study of marriage and family life has shown that kids from even semi-stable nuclear families tend to be significantly less prone to the pathologies common in the black lower class (where out of wedlock birth is the norm, not exception). Ever deal with white trash (not rednecks, white trash; there is a major difference)? It's the same sociological situation and even the same set of behavior problems and stunted options despite "white privilege."
A large part of the problem is that there is an active segment of society that doesn't want to deal with the moral issues that lead to this situation, denouncing that as "moralizing" and instead wants to focus purely on politics as though it's not all intertwined. Yet those issues are precisely the personal choices, enabled by public policy and culture, that lead to the destruction of the stable nuclear family in much of the black community. Blaming external factors for everything, which is the politically correct solution, is like Josh Duggar attempting to blame porn and Satan for why he graduated from molesting his sisters to serial adultery against his wife.
