The most regressive culture in the history of mankind; the American urban black culture. Yet we are required to worship it.
It used to be the lower class tried to emulate the culture of the classes above it. Since the end of WWII (It accelerated in the 1960s!) it’s been flipped. The upper classes emulate the classes below them. It’s all very egalitarian. The flatter the society is in its culture the better or so we have been told.
