The Apollo Program, Academia, and the BBC all pay their workers, which makes it profitable for them to do the work. I get your point: These are not for profit enterprises and they still get important work done. I'm making a different point: People don't work for the benefit of others without being rewarded. Open Source Software is not a bad counter example. I think there are rewards in the joy of programming, making a name for yourself, and a few other things, but I'll concede that there is some nuance there.
