>In reality, what they are is just better at hiding their racism and xenophobia.

It's not xenofobia, it's just a rigid caste system with little to no upward mobility for immigrants, setup for the economic benefit of the locals at the expense of most immigrants. Sweden and others for example has no inheritance taxes so locals inheriting property and assets get a massive leg up at advancing in society with little effort, over even the hardest working immigrants making the system feel unfair and rigged against you if you're a high earning immigrant paying high taxes. Something less of an issue for immigrants in the US.

Xenofobia implies discrimination based on skin color or ethnicity, but that's not the case here, as white european immigrants also fall under this trap because they don't have the citizenship, language, bureaucratic system knowledge, connections, inheritance to get the chill lives the locals do, and get stuck in less desirable jobs with little to no upward mobility even if they learn the language. I'm EU native living and working in another EU country and feel this regularly across all society along with the other immigrants I know here.

> The majority of US immigrants are skilled.

Maybe in SV tech companies, but most illegals to US are not skilled, but they're tolerated as long as they don't break any major laws because they do the tough and dirty jobs for low pay the natives don't want to do otherwise they risk deportation.

The difference is EU doesn't do deportations and instead showers illegals with welfare, meaning they're not forced to integrate and become self sufficient ASAP like in US, and it's easier to stay a perpetual victim in need of state assistance.
