I think people who have attitudes like this are misguided. If you don't like working for Elon or at Tesla, don't. There is only one Tesla while there are tons of other companies you can have a "good" work/life balance at.
That's true to some extent. You should be able to choose a job that is a little less stressful but pays a little less, or the opposite.
But there are a lot of caveats. For example:
First of all, a company sets standards in wages, benefits, and hours to the extent that it is a monopsony [1] in its particular geographic market and labor market, and also insofar as there is unemployment in the region (and, thus, there are people who could take your job and it would be hard for you to find another job). Tesla is a very large employer of unskilled labor, as well as skilled. The Bay Area doesn't have as high unemployment as other areas, but it still has some. Therefore, the labor conditions at Tesla impact labor conditions at other workplaces to some extent.
Second, more on the level of values, why should a worker have to miss his daughter's ballet recital on Saturday because his manager told him on Friday afternoon at end-of-shift that he has to come in tomorrow? That should not be necessary in a well-run factory. Maybe it would be different if a factory worker at a Tesla factory could participate in the vision by buying a Tesla car, but that's not possible either because they're too expensive.
