You're right! There are many people who want to be artists! There are many people who find happiness and fulfillment in nature, civil society, activism, music, and more. These people want these things desperately and they want to not have to work to do them.

You're completely right. There are lots of these people. I simply do not believe that this number is large enough to significantly alter the analysis I have offered.

Am I generalizing? Of course I'm generalizing. There's no other way to meaningfully talk about tens of millions of unique, special, individual human beings.
