Exactly, it's the stadium that generates the revenue, not the player. Your goal is to compete to occupy the largest possible stadium. Excerpt some owners don't share as much of the revenue for a given sized stadium... it's up to the players to insist on that.

Another way to look at it...

Pilots are only worth the lowest common denominator (ie regional FO) and that is determined by market forces. . Any pilot who gets paid more than that is a special case, and management only tolerates that if the plane in question has enough capacity to generate revenue.
