Art school provide a wonderful playground of networking. This could be the price to pay. Problem: with networking, you cannot be sur that because you paid the fees it will help you with your "career" (if it can be called this way in the art world).
Anybody pretending that it's possible to do art without being a "nose-browner" lies.
Anybody pretending to be a "creator" often forget to cite his/her sources and influences.
I am not very astonished that, in a domain like art, that stays a dedicated way for higher classes to demonstrate their superiority by owning costly art, prices can be so high for education. But I don't call it an art school, I call it a bank.
