> I've done that math too and the other reality is that most of those costs are optional in the US.

If you're very young, single and childless, sort of. You can pick the lowest tier of health coverage from your employer which is often fully covered by the employer and have no other major costs. If you're young and single and healthy this can work out. Of course, if you have some kind of accident or medical emergency, expect to be bankrupted, which is not how it works in other countries.

But once you have to cover childcare and school and university, and the lack of time off for parents (add expensive babysitters on top of daycare and school) and pay for good medical coverage for a whole family and of course contribute maximums towards retirement because social security won't be there and so on. Suddenly that large gross salary is mostly gone and what little is left over isn't very different from what may be left over from a much smaller salary in a different country.

And of course here in the US we get to work our nice 60 to 80 hour weeks instead of a regular 40 hours and disconnect from work. And we might two weeks vacation, if you can afford to take it, instead of 4 to 6 weeks.
