"I think what happened in the last 10 or 15 years in the art market is that all the players - and that includes artists, dealers, art advisors, everyone - basically became dealers. We've had old-school collectors morph into speculators, flipping works. We've seen auction houses buying works directly from artists or from sleazy middlemen. The last step before the crash was the artists themselves supplying the auction houses. Dealing themselves, you know? The art world is as unregulated as any financial market there is."
