How do you know they’re able to? Looking at Disney as a specific case, they’ve lost over 1 billion on their movies in the past 2 years and are constantly bleeding subscribers. On top of that there’s also some persistent rumors that they got caught up in the whole FTX debacle and lost a bunch of money on that as well.
Also, as a quick aside: what would you consider to be fair to their workers? The wages I’ve heard being mentioned sounded pretty good to me already, especially compared to other jobs.
