Art is never a luxury. Life has an inside as well as an outside. Consumer culture directs all resources and attention to life on the outside. What happens to the inner life? Art is never a luxury because it stimulates and responds to the inner life. We are badly out of balance. I don’t think of art / creativity as a substitute for anything else. I see it as a powerful expression of our humanity – and on the side of humanity under threat.
If we say art is a luxury, we might as well say that being human is a luxury.
