that's a textbook example of survivorship bias.

those who would benefit from migrating to Europe cannot afford to, are greatly discouraged or straight up can't (passport, language barriers etc)

OTOH most of those going to the US right now are from eastern Europe, following the flood after the wall fell.

Or people who are going there to increase their salary, not necessarily their quality of life. I have several friends who are working for one of the FAANGS in the US but come back to Italy for medical check-ups or holidays because here's cheaper, safer and it's a better place to spend your free time or raise kids.

European population in the US is pretty stable though.

In the end people of European descent are still the largest ethnic group in the US of A, the USA were founded mostly by anglo-germans while the opposite has never been true.
