""I don't agree with auction houses selling street art - it's undemocratic, it glorifies greed and I never see any of the money." - Banksy He's happy to make money selling his paintings to celebrities so how can he really take this position? His prices put his gallery out of the reach of the average person. He was happy to play the art market game and has done well out of it but now he's on the losing end and doesn't like it. The only thing that has really changed is that he doesn't get the money.
