That's complete bullshit. If I were to open my big mouth and "fight for quality" at my place of employment, I'd be fired,
I knew you would go there. Fine. Let's argue this point.
Employment is supply and demand. If you're unhappy where you work, and you feel you have alternatives, you leave.
The reason to be unhappy in a creative profession could be that you feel you're having to attach your name to crap and take the blame for it.
Do you really think that nobody in Hollywood takes a pass on work they think sucks? Do you think that nobody in Hollywood regrets taking on work that turns out to suck and tarnishes their reputation as a result?
My definition of a hack is someone who wilfully decides to produce crap. They cash the check and don't rock the boat. It means they either don't feel they have enough talent to get another gig or they just don't care that much about quality in the first place.
This is not some migrant worker who feels they can't quit their janitorial job and has medical bills for his kids. This is a high priced executive who should be able to write his own meal ticket, who produced crap, and then tried to pass the blame to Paramount, and has been partly successful based on the people who are rallying to his defense in this thread.

Look at Leonard Nimoy stories that surfaced recently (from Michael Eisner's bio) about his reticence about rejoining TMP, and the rationalizations he used to join, and the way (so he says) that he tried to work unofficially with Shatner to improve the last act, and how that experience colored how he approached II, III, and IV. This sort of judgment call as to whether to play along or not and how it might impact your reputation happens all the time. It's not true that everyone just keeps blindly feeding at the trough and never tries to protect quality, nor should rocking the boat be seen as putting ones family's livelihood in grave danger. It's an absurd exaggeration.

Here's another example. Denise Crosby leaving TNG. She felt she had nothing to do anymore, that the character was kind of already being written out of the show anyway. You can argue that she didn't have better prospects and should have hunkered down, but it was a judgment call that by staying she'd be a glorified extra. I could see her rationale. Do I have to go down the whole list of Trek actors or behind the scenes people who decided to quit for one reason or another?
