I'm sure the majority of actors would love what you're saying. Most actors don't get anything close to a living wage.
Now, sure, a few lead actors do, but then they're worth it. They pull people in to watch the movie so that it's capable of making its money back and paying something slightly less shitty to the other actors.
The other problem with the "We don't want actors earning outrageous salaries like $250,000 per movie!" (seriously, that's actually not unusual for a headliner) argument is it ignores context. Acting is a shitty career. If you're unsuccessful - and you probably will be - you'll end up leaving penniless. If you succeed, well, you have an expiration date (not a massive market for older people in Hollywood) after which you'll probably be incapable of useful employment because you just wasted ten years on a combination pretending to be someone else, and serving customers at cafes to make ends meet. You'll have next to no useful skills, beyond being available for bit roles in TV shows.
I'm not saying Hollywood is the most efficient of money making industries, but the salaries, at least, are, if anything, too small, largely because it relies upon unrealistic eager dreamers hoping they'll win the popularity lottery and get to be the next Brandon Routh or Kate Bosworth.
