European salaries are laughably low even compared to low ball offers from US startups.
Essentially options for good (but not great) sr engineers are
1. Get 120k salary in Europe (on higher end)
2. 500k at FAANG in US (salary + RSU)
3. ~200k at startup in US + lottery tickets
Both option 2 and 3 strictly beat option 1 (especially after taxes) so European should get off the high horse and recognize reality that they are poor and exploited by companies and government.
