Presumably, you leave to go work for another company, so none of these are a problem.

So you’re not aware how much a visa screws you in the job search? And you’re not aware how much time raising a family takes from searching for a job? And you’re not aware of the fact not all doctors are in network for all insurances, that your new insurance company can and will deny your dependents their medication to force them to take cheaper stuff that doesn’t work, again, to prove it doesn’t work? And you have to sit and watch your wife or your child or whatever be hospitalized and crash and know it’s just what happens when you switch jobs?

Yeah correct, my experience is just locally, and the healthcare isn't that bad here.

US is just simply has a system that's very cons for employees, especially with visa and right to work law.

I’m not the OP, but I don’t think you understood her/his comment. People leave jobs.
