Is art more a descriptor or former of societies?  The Nazis appear to have thought the latter.  Hitler wrote (link):

“If some self-styled artist submits trash for the Munich exhibition, then he is a swindler, in which case he should be put in prison; or he is a madman, in which case he should be in an asylum; or he is a degenerate, in which case he must be sent to a concentration camp to be “reeducated” and taught the dignity of honest labor. In this way I have ensured that the Munich exhibition is avoided like the plague by the inefficient.”
