But there's no way round it-commercial success is a mark of failure for a graffiti artist. We're not supposed to be embraced in that way. When you look at how society rewards so many of the wrong people, it's hard not to view financial reimbursement as a badge of self-serving mediocrity.

The Art we look at is made by only a select few. A small group create, promote, purchase, exhibit and decide the success of Art. Only a few hundred people in the world have any real say. When you go to an Art gallery you are simply a tourist looking at the trophy cabinet of a few millionaires

We can't do anything to change the world until capitalism crumbles. In the meantime we should all go shopping to console ourselves.
