1) art is dangerous and morally corrupting (film censorship) or a distraction from action in the world
2) art is is morally uplifting and a force for good creating social cohesion and individual confidence
3) art can only be valued on its own (aesthetic) terms and shouldn't be 'used' for other ends
Everyone gets interested in art when the government is spending 'scarce' money on it...
