To get to the Baumol effect, the movie actor can perform once and be seen by millions whereas the theater actor has to perform at least once a night in front of one roomful of people. So the former can get paid more, a lot more.

Probably the highest paid athletes in the world are european soccer players and the thing there is that these salaries can be justified in terms of the value top players bring in a game where being relegated can bring the money train for a team to a halt. You don't see working-class soccer fans complaining about this (they feel the value!) but the owners and many representatives of capital get fuming mad about it.

(Funny, growing up in youth soccer in the US taught me to think of the game as an exercise in Brownian motion where there are too many people on the field who aren't held accountable. It wasn't until I had an argument with a recommender system that couldn't accept that I hated soccer that changed my mind and turned me into one of those sports fans who rolls out of bed Saturday mornings to watch the Premier League that I realized how high the stakes are in the European game.)
