Considering that the vast majority of people who make a living as artists work for corporations, rather than for themselves, and also seem to be far less talented than independent artists or hobbyists with some other form of income, I think your "solution" would actually exacerbate the problem that you're drawing attention to. Bear in mind that entertainment corporations don't really need to compete in the free market, since they are subsidised by a handful of obscenely rich wankers with an agenda to push. This is the reason that the products of dynasties are usually so unbelievably incompetent.

Small-scale studios and independent artists, on the other hand, are free to concentrate on making art that is good, and should they succeed in the free market, they can quit their day jobs.

@jacobtothe, care to provide your two units of currency?
