Gross definitely, but net (after taxes, healthcare, housing and other fixed costs)... not so sure. High CoL - seriously even as someone who lives in Munich, US housing prices are utterly incomprehensible, just how the fuck do y'all even manage to survive?! -, high costs for transportation, the utter madness that is US healthcare, hundreds of dollars for cable TV, having to save for your pension or student loans.
I'd wager that even after accounting for taxes, most Europeans have more money in their pocket than Americans working in the same field.
(And obviously, all of us have it vastly better than 99% of people in Africa)
