How many of those $10B companies are actually really worth that, not just an inflated result of funding rounds.

The 420 or so players in the NBA can largely be considered to be the best 420 players in the world.

NBA teams also have a pretty high revenue to value ratio.

Points to you too for ignoring that in many cases the salary of a Fortune 500 CEO is, in many to most cases a much smaller fraction of their compensation packages. In many cases bonuses and other compensation is between 3 and 10 or more times the salary, so not exactly equitable, though it makes for a better sound bite.
