Modern art was funded & propped up by the CIA, they claimed it was to fight communist influence in art & media.They created the Congress for Cultural Freedom, that trained intellectuals, writers, historians, poets, and artists which was set up with CIA funds in 1950 and run by a CIA agent.
If you look at any art and media institution today they have all turned into communist cesspools, maybe that was their plan all along.
Hidden Hands – A Different History of Modernism part 1 is a good documentary explaining how they took over western art institutions and changed western art from beautiful Norman Rockwell's paintings to Jackson Pollock's abstract expressionist trash. The documentary is presented from the CIA's perspective, it tells the audience what they did was a good thing and art & design progressed because of them.
You can read the book that this documentary is based on to find out more about the organizations & people involved in the destruction of western art & culture.
