The New York Times has a recent article that addresses the hunger of some dealers for the work of emerging artists. The article states that there is not enough good work out there for a burgeoning market.
Perhaps they should learn to navigate the wide lands beyond the borders of New York City. Really, it's not that difficult, especially since so many large metropolitan areas actually have comprensive transportation systems in place. And if they think that the prices of student work in New York MFA shows is reasonable, maybe they should look at the prices for the work of mid-career artists who are producing in, oh I don't know, Pittsburgh? Philadelphia?
Another suggestion for this art-hungry market? The internet! I dare you to run a search on your favorite search engine for contemporary art. You can even be specific and search for work in just your favorite medium. You'll be overwhelmed.
What are you afraid of? Making up your own mind?
