You bring up some interesting points.
Did you know that the CIA funneled huge amounts of cash into making modern art as a response to Soviet realism?
Did you know that the CIA also had its hand in cultivating the post-Marxist left?
I'm going to respond to OP in a top-level comment soon with some reading recommendations about how modern art is a CIA op or, at the very least, the CIA pushed modern art into the mainstream via massive amounts of monetary support. You might be interested in reading some of the books that I mention.
