Definitely it depends on the country, the industry, the specific company, and by the definition of mid-career (10 years? 20 years?).

But then again, other countries do not double-tax from the start, so none of the international coworkers of the Americans abroad have to pay any taxes to their home countries, or for specialist accountants to deal with the differences in taxation.
Americans have a big burden of FATCA, specialist accountants and just a lot of stress in general.
And to what end, when most of them end up paying no taxes to the US whatsoever? (this was the point I was trying to make - that after all this BS they are put through, the US is still not getting any extra tax revenue from these people)
It seems like it's mostly so that US politicians can say they've done something about high-profile rich people who have moved to tax havens, rather than actually increase tax income measurably.

I know a bunch of Americans abroad, none of them have to pay any tax to the US, but several of them have to pay specialist accountants to deal with the differences in taxation between the countries. It ends up being a tax on Americans that is not paid to the US but to accountants.
