People will buy Bush's paintings because of who the painter is, not because of the quality of the art work -- same reason they pay money for a George Zimmerman painting.
It's not about art; it's about commerce.
All art is about commerce.
Absolutely not. That is not true. People who know nothing about true artistic value might think so, but it is not true at all.
You need a pin in your bubble. Art is about commerce. If you can't sell your shit, you are a worthless artist. Rent a storage space. Decorate that.
