Sports is one of the places where there is the clearest trickle-down effect, though, one of the very few. For example, Aaron Rodgers' contract, or Manny Machado's. There's a lot of distortion as to the player slices of the pie in the major American sports (generous minimum salaries in exchange for restrictions on freedom to change teams, for example), but there's no doubt that major league players do benefit to some extent from the legalized cartels that are the four major sports. Some are harmed, of course - NBA players whose market salaries would be above the max, for example - but on the whole the effect is almost certainly beneficial to their pocketbooks.
All of that is contracted, and even the high salaries probably represent a restraint on trade favorable to ownership- if there were no standard player contract, no cap, and no restrictions other than those contracted for by the player, Rogers and machado would likely have far more favorable contracts, meanwhile those at the bottom- practice Squads, guys without signing bonuses in the minors, even nba summer league invites (which is televised and monetized by the nba) have terrible salaries and job protection.
Compare that to ownership which has a cap on what it can spend on salary, a slower of talented players who can be forced to play for them (unless they want to change professions), and heavy revenue sharing. Not to mention federal and local legislation and regulation to ensure that, no matter how incompetent, they can’t fail.
