Vocational awe is a curse. If you have an endless supply of people willing to work pennies then the industry will build itself around paying them pennies. This does not mean that this is the only way you can build an animation industry - just that this is the path Toei and Sunrise took.

The amount of money that goes into the industry is not static. The original linked article specifically cites cases in which members of the production committee (often toy companies like Good Smile[0]) decided to deliberately take less money because they didn't want their control diluted. They're only able to do this because they can fleece animators into working longer for less money rather than having to get more capital in the project.

As for animators having to find new work... good? The current situation is one in which animators pursue their passions, and then have their passions completely take over their life and crush their soul. If they quit en masse, that would be backpressure against productions that want animators to fall on their swords, and production committees that want shit done cheaply.
