Actors get paid millions of dollars for doing a job that's relatively easy. Now, I'm not saying that I could act as well as Tom Cruise, etc. I'm also not saying that there are no difficult aspects to the job. However, many other jobs (garbage man, computer programmer, etc) are much more difficult. But, actors still get paid more.
Now, people find out that actors don't even have to act any more. They don't even have to look like a supermodel. It's all done by computers. And they still get paid rediculous sums for making crappy movies.
If it's all digital now, why can't anyone be a movie star? Hollywood has always looked corrupt--rampant with cronyism/nepotism/etc. They talk about "getting your big break." Very often, the "big break" comes because you're Francis Ford Coppola's sister/nephew/etc--not because you can act. This is what pisses people off. The digital technology can be used to keep the talentless princes and princesses of Hollywood in power/money.
