Healthcare: We're talking about tech jobs. The healthcare coverage you will get from any tech company paying 6 figures is going to be essentially zero cost full coverage.
Stability: I have no idea what you are even talking about here, but it would be pretty hard to refer to the US as unstable from the perspective of someone working in a tech job. I suspect you pay too much attention to click-bait news and not enough talking to people that live here?
Democracy: again, what is this even referring to? The fact that the US is a republic? That's a pretty weak argument when comparing to a monarchy.
