Did you go to Eton? no? Was your degree taught in a 300-year-old building where your grandfather also learned? No? Then it's not supposed to help you appreciate Hirst and Koons. It's supposed to help you appreciate Kandinsky and Magritte. You know. Stuff you can buy prints of at Ikea.
Banksy is like the Wyland of contemporary art. He makes stuff that the general public can absorb while getting the wealthy to pay for it. That way they can still feel a little street. They're not out of touch, it's all their friends who are out of touch. And see, if they have a Banksy and a Warhol and a Hirst they're real people, not like that bitch Veronica and that ghastly Mark Quinn she hung in her study after she made sure everyone knew how much she paid for it.
