I've seen a few people grouse about "how much" actors and writers make. The common—and correct—rejoinder is to point out that most of them don't make that.
But another element I think needs to be pointed out there: the ones with money are right now _fighting for the people who don't make that kind of money_. They are doing it for the ones who come next. For the writers and actors who are just now entering into the market.
There's a lot to be said for that as well.
