The article you linked is about revenue, not profits, but that doesn't really matter for the argument.

I don't think you can divide $X revenue by N employees and say that therefore there must be some employee pulling in at least $X/N revenue, or at least say that in a way that matters. Imagine a hypothetical tech startup with $1 billion revenue and 10 employees. Is one developer there necessarily bringing in at least $100 million? Would you hire that developer for $50 million and consider it a deal? What if most of that $1 billion came from a single government contract with a serious conflict of interest?

Anyway I think that working for a large organization at a big salary and coming out morally ahead is theoretically possible but very difficult. I don't think I'm cut out for it, myself.
