I think what might be more problematic is our systemic bias toward attributing the "credit" (monetary and social credit) to any significant work to one person. This just causes pretty much any collaborative work that is not between "pure" friends to devolve into resentment.
I think this has deep roots in American individualistic philosophy, and it's an example of how damaging it can be.
Well Steve Wozniak also became a billionaire, so while Jobs may have gotten more money but he also ran Pixar so it's not all that one sided. As to the "collective" effort argument that IMO that often get's into a social constructs where people are expected to sacrifice for the company and get rewarded for it. Where I prefer the concept of people who are directly compensated upfront for there efforts vs the social contract of working for a promotion etc. You can't be cheated out of a pension you where never supposed to have.
