a) money make up for a lot of systemic deficiencies, adding here taxes, which are insanely high all across EU, salaries are several times lower here too

b) English language as a first class language. For example, while there are many job offers promising English only requirement, in reality a significant part of these unofficially presume you will speak local language at proficient level in the team, and hiring process filters for that.

c) EU countries have a lot of their own bureaucracy hell regarding immigration. For example I'm now on a Blue Card status in EU, that's a high skilled immigration program. I need to renew my card for the next 1 to 3 year period, I've started process in Sep 2025 and best case scenario will get card around next winter 26/27. Worst case scenario, add half a year more to that. If I want to get a passport, originally I had to dance through these hoops for at minimum 9 years. Just recently it increased to 11 year. And right now there is a law proposal in the parliament, increasing this term to minimum 17 years (among other inane requirements). If that passes, they may increase it even more in the future, making all immigrants live on the flimsy status for decades. USA at least makes the process faster, even if unpredictable.

tl;dr - EU is nice, just like USA is nice in it's own way, but in both countries immigrants have to put up with a lot of legal BS.
