Art since the 20th century particularly in the U. S. seems to me so often to begin as a panacea for the poor/non white/uneducated, which when it spreads is appropriated by the rich/white/educated.
They quantify, strip and dissect it so they can spoon feed/teach it to themselves and their children with no understanding of the source. They theorise, pad and distort it. Then disseminate it to themselves to the exclusion of the originators.
Jazz, blues, rap, graffiti, (over sized clothes = low bum trousers!)
