There's nothing new about this - income inequality is a big issue throughout society, not just in the arts. However, the cash-starved nature of the arts makes the problem more acute. If the only way to earn money is through exposure, and the only way to get exposure is to spend thousands of hours making (and marketing) art that you could otherwise spend earning money, the people who need to earn money now are at a major, perhaps definitive, disadvantage. As a result, over time, you would expect to see more and more people who were lucky enough to have a cushion early in their careers (if not on an ongoing basis) persist to become professional artists, and fewer and fewer who have had to do it completely on their own.
Seriously, Doug McLennan should bring this guy on, posthaste.
