I'm not sure the data matches that line of reasoning. Looking at number of immigrants per capita for various countries, the US is beat out by some of the countries you wouldn't expect from your conclusion. Notably Australia, Switzerland, New Zealand, Canada, Sweden, Austria, Iceland, Germany, Ireland, Belgium, and Norway all have more immigration per capita than the states it seems. https://worldpopulationreview.com/country-rankings/immigrati...

An Austrian who immigrates to Germany or even a German (or other EU national) who immigrates to Switzerland has a very different experience, both in terms of legal hurdles and likely relative earnings than someone immigrating from Latin America to the US.

How about if we look at immigration into the US as a whole vs immigration to the EU as a whole? What do the numbers look like, then?
