First of all, that guy is full of ****.
The art industry depends on people like to make their business legitimate, but it's not always for the better. Compare the art industry to more traditional industries like manufacturing or finance - without standards, rules, and predictable patterns, it's nearly impossible to quantify what's going on, what something is worth, and who is winning. It's easier for a person or organization to sell tons of high-dollar art when they can "objectively prove" that it is, in fact, finer art than the next guy's art.
Unfortunately for the art world, there are established formulas for selling massive volumes of uninspired, soulless "art". It's like pop music - it's technically perfect, it uses algorithms to appeal to the largest audience, and the record labels decide what's going to be a hit and what isn't before the song is even recorded.
My point is, this guy is speaking purely out of self-interest. He's selling art school, and I wouldn't be surprised if he didn't even believe half the **** that came out of his mouth.
