A friend who works in entertainment makes $9.45/ hour and I think they get a very minimal raise each year (like 20 cents or so) so I definitely don't think that's a fair pay. Especially considering competitor pay (universal employees make about 11 starting in the same positions) and compared to "face" characters who arguably do less/equal the amount of work as "fur" performers... It's stupid. Like others have said, you know what you're gonna make when you get hired and have options to go elsewhere, a lot of people just love the company. It doesn't mean they can't complain about their wages; I think that Disney cast members would be of the quality they were a decade ago if they were paid reasonably.
You are right... but I must wonder why would someone take a job if they think the pay is too little... complaining after you have taken the job would seem to be a recipe for being discontent and that will show up in your work.
