You should read Seven Days in the Art World if you want a look behind the scenes of the fine art community:

EDITED to add: Brief summary stolen from a reviewer since Amazon doesn't really give one:
"Over the span of five years, cultural sociologist Thornton visits seven different stages during the rise of mass contemporary art consumption: Christie's auction house in Manhattan; a critique session at a California Institute of the Arts (CalArts) seminar class in Los Angeles; Art Basel in Switzerland; Tate Museum's Turner Prize competition in London; Artforum magazine; Japanese artist/celebrity Takashi Murakami's studios; and Venice Biennale."
I'm a former art student and have a particular interest/knowledge of the art world. The world of art forgery is more profitable than selling stolen art on the black market—the general problem being that stolen art is too famous to sell.
Heck, if you wanna talk about profitable, contemporary art itself today is pretty much money laundering. Recommended reading: 7 Days in the Art World. 12 Million Dollar Stuffed Shark. The Forger's Spell. The art world is crazy and if you really want to do something interesting with it I suggest learning a bit.
