As Aesop so eloquently pointed out, good acting is a rare skill. So is throwing a curve ball, catching a pass, running hurdles, and any other thing you can think of in sports. The number of people that can perform them well is very limited.
The example of Olympic sports comes to mind, however, when considering compensation rates. There are Olympic sports that are just as difficult as playing Major League Baseball, or NBA, or pro football. Starting as a young child, investing thousands of hours in training and skill development, becoming one of the top athletes in your chosen sport, and even winning a spot on the podium at the Olympics does not translate to a multi-million dollar paycheck.
There's a reason for that. As difficult as your sport might be, no one is willing to pay large sums of money to come to a stadium every week to watch you perform it. Advertisers and television networks aren't making billion dollar deals to broadcast your sport every season. Product endorsements might bring in a few thousand dollars instead of the millions that the pro league athletes earn.
That doesn't mean that all these world class athletes aren't amazing at their sport. They are. We can't do what they do. That isn't the question. The question is how much are we willing to pay to watch them do it.
Great actors, directors, designers, editors, and all the other people necessary to make a great movie, we can't do what they do. The question is, and always is, how much am I willing to pay to watch their creation? If enough people pass on a movie, it loses money. It's more complicated in the modern age, it's not just box office receipts, it's streaming and overseas returns and sales, but the bottom line is still there.
We are all selective about what movies we watch. On line reviews, Rotten Tomatoes, YouTube trailers,word of mouth from friends, it's rare to just go see a movie. You're investing time as well as money and you're hoping for value. A great movie, in any genre, is a treat. It makes you think, it takes you into another world, it becomes something you talk about with friends.
But it still depends on the money from the viewers. It always comes down to that. And if the actors, directors, or anyone else in the industry wants to preach their personal political views and it causes the viewers to turn away, then those movies will lose money and the next movie won't get made.
