I know offhandedly that at one point it was possible to live on one's short fiction but now that's been entirely squeezed out. (Unless you're Ted Chiang.)
Like, for example, let's just consider authors and video game creators. Let's suppose that in the fifties, before video games, there were, say, 100,000 full-time fiction authors in the US. (That number sounds awfully high to me, but maybe.) Today, according to this article, there can only be at most about 7,000 full time fiction authors in the US. But according to this page[1], there are 260,000 people working in the videogaming industry. So if we only consider these two industries, that's 160,000 more people getting paid full time wages to create entertainment.
That's sad if you want to be an author, but if you're concerned about the overall creation mix of society, then maybe it's not so sad.

And the slice of the videogaming industry that is analogous to authors is probably a vastly smaller proportion than of print fiction publishing because there is so much more non-authorial stuff to do.
I have to admit I'm a little surprised. I would have thought by now the videogame industry would be bigger than books, but maybe it's not.
