How big is the market for art and other entertainment? We already having "starving artists" with the limited pool of artists that we have now. Even supposing art consumption exploded, people generally don't consume a lot of lower quality, amateur art. Compare the earnings of a musician on the billboard charts to, say, the most popular local band in your city. Similarly, compare the revenue of a major league sports team with a minor league team. Both of these demonstrate that only the elite entertainers have enough success to quit their day job. I don't expect this pattern to change, only for the number of elite to grow slightly.
