> how they prefer to work 600 hours a week instead of having forced days off
Your idea of jobs in the US is wrong. I work 40 hrs a week and sometimes that goes up to 45 or 50 but not often. I get breakfast and lunch provided to me (also dinner but I don't stay for it because I would go insane) and I make 150k + 80k a year in equity. You could also however work at amazon and get paid the same but also work 60 hours a week (Amazon is the exception and has a very bad reputation).
> health care through Employer is so much better than through government
Health care through the employer can be significantly better than through the government. It can also be worse.
If you are a high performer in the US, it is perfect.
