Just for reference, converting to USD $150k be in the top 6-7% of earners in the U.S. in 2022. Taxation rates vary widely.
I budget for ⅓ off the top, living in NYC (this is an overestimate, but common practice) for a post-tax income of $100k. High income geographies are correlated with high tax rates in the U.S., too.
Anyways, all this to say that U.S. post-tax-post-benefits income is not wildly different from the E.U. Maybe the main difference is that you can work as a freelancer, expense everything, and effectively opt-out of health insurance, and take home more salary.
But if you're salaried and in tech in the top quartile of the labor market, post-tax savings is pretty much the same in western EU vs U.S. There's no 10x difference in wages, (excluding equity performance, which is not a tax/benefits policy issue).
In general, E.U. citizens I know who have come to the U.S. do it because the businesses here are more interesting and have more upside (i.e. the aforementioned equity upside component). If they're making bigger heaps of money, it's because of startup equity comp, not because of tax or benefits policies.
