Somewhat inspired by this questionthis question, I was wondering what kind of jobs Superman would pursue if he had an agent. He would obviously become the orbital delivery vehicle of choice for basically everyone, but I have to wonder what kinds of things he would end up doing on a daily basis for maximal profit.
Assuming Superman exists, but that he doesn't have to deal with supervillains on a regular basis, what jobs would Superman pursue for maximal gain and therefore maximal giving to charity?
For the purpose of this question, assume we can't really learn much by studying Superman since all we can really measure is what he does, not how he does it.
