In Los Angeles, I've met a lot of people and some work in the film industry. Not celebrities or anything (I'll address them too) and they talk positively about their unions. Hollywood is ALL UNIONS. It might be the biggest union in the USA that doesn't call any attention to itself. Everyone from truck drivers, cameramen, and lighting guys to Brad Pitt and Quentin Tarantino: All union people, all working for different wages but having the security of union representation.
Of course, the fees to get into a Hollywood Union are steep and it's tricky to get in but I have a friend who's a young guy making a ton of money as a crew member. Yes, they work long hours and the schedule can be weird (4 weeks on, 3 weeks off) but they get so much that it just goes to show unions are the way to go but nobody wants us to remember that.
Hollywood isn't Steve Spielberg (though he is still a union man), Hollywood is the tens of thousands of average, non-college graduate, working-class people who worked their way into an iron-clad union.
Whatever you think of rich celebrities and the movie industry just know (unions have their back)
