Marvel is the primary offender in this arena because they release three tentpole blockbusters a year, and then on top of that, four TV shows. So they are kingmakers in this industry. By not knowing what they want, and by over working these employees who are already so few in numbers, basically it's a race to the bottom. And the film's declined in quality, the fans' revolts, they earn less money,. The population of qualified workers is that much closer to complete burnout.
