You're talking about athletes and singers. But the vast majority of those employed in these industries are not the pretty faces. They are the producers, the audio technicians, the trainers, the vendors at the stadium, the men who swap kegs at the game. The lighting directors on the movie set. The CGI artists. The bouncers at your favorite venue.
My point still stands. (1) All of those support jobs are still tiny compared to the employment of other industries. (2) Many of those support jobs can be either automated away, or barely pay minimum wage. (3) Most of the support jobs that DO pay well still have the dynamic where a top tiny percent make the lion's share of income. The best CGI artists make multiples more than good ones. Same thing with Hollywood personal trainers, same thing with lighting directors.
