All the benefits OP lists are at or below mandated minimums for Western EU countries. It’s trivial to lookup and confirm for yourself.

In software the money difference you still end up ahead of where you would be on an equivalent salary in the EU. Also last time I was considering a move to the EU job market was weaker than the US. Also you still need to get all the necessary work visas which aren’t automatic. Even as a dual citizen I can’t just show up to work at a company in the EU.
