I think you're forgetting the risk involved. To me, of course, it's the money because there are plenty of ways to get the satisfaction you're describing. It may not even be a crass need for money but people who live in poorer areas of the world taking a job and earning a cut as possibly the only worthwhile means of using their talent.

It's not as if worthwhile outlets for talent are easy to come by. It could be easier. The world we live in does not prioritize this outcome.
