Why isn't anyone pointing out it's likely the median US engineer is far above the median EU engineer skill wise and talent wise?
Let's look at it this way, if the top 5% of EU engineers can make literal millions in a few years working in the US, at least some percentage of them will end up in the US.
Then let's consider that money influences what careers people pick. If very high IQ people who are ALSO ambitious see that they can choose between going the MD route, or finance, or SWE, or big law, and all of them are somewhat equally lucrative, some large % of those ambitious high IQ people are going to go into SWE.
In the EU if the only way to big bucks is finance or consulting, and SWE is a normal peasant like life stlye, aren't ambitious high IQ folks going to be more likely to choose finance or consulting instead of SWE?
Isn't it likely the median US programmer, because of incentives, is going to be higher than the median EU programmer? This isn't to say there aren't brilliant EU programmers or that the US on average is smarter than the EU, it's just a combination of brain drain and what smart people end up doing.
