Regarding healthcare, sure a US worker may be well taken care of while employed at that company, but what happens later? A US friend, his father, after decades of well-to-do middle class lifestyle, unfortunately got cancer while between jobs and not properly covered by health insurance. I believe that as result the family were worried about having to sell their home, at a time when the real estate market was falling. This could happen to anyone in the US, today's high-flying Google engineer could later have some kind of health problem (especially given some of the lack of food standards or pollution controls in the US - not that I'm saying Europe is perfect either...) then they lose their job and their insurance. As result, if you intend to live the rest of your life in the USA, it seems to me you need to amass some "danger money" to deal with health problems, for yourself or loved ones. Therefore a decent chunk of your salary needs to be used for this, and invested properly to keep pace with inflation which can be a pain/hassle/time sink . That then doesn't make those super high US salaries look so superior. And 1 more thing, price of basic fresh fruit etc, non-junk food in the US seems very high to me compared to other countries
