Secrets can actually be quite important. A work of art that reveals its meaning or its power too quickly is uninteresting. It might not even be a good work of art.

The art market does represent a sort of hyper-capitalism: it produces added value without any actual work being done.

It's no longer terribly sexy to own shares in certain companies it used to be that being a shareholder in a corporation would connect you with it. The result is that people really want to invest in valuable things, and contemporary art has become a very stable material value with great growth potential.
