Question: How does accepting more immigrants "legal" or otherwise help the American middle class? : neoliberal

The answer is comparative advantage.

A 67 IQ Bomalian is never going to be a doctor, an engineer, or a lawyer. And there's a good chance none of his descendants ever will, either. The best shot they will ever have is driving a bus, being a garbage man, wiping the asses of hospice patients, etc.

So what good does flooding a country full of literal r-slurs do? It means that those just above them take their skills and move away from sectors where they in competition with migrants and move toward sectors where the migrants cannot compete, or at least not as well. Picking vegetables is a job that requires zero skills, so admitting a bunch of Squatemalans pushes the White unskilled into, say, the service industry, where knowing how to speak basic English is more useful.

Think about it this way: if there was a city full of clones of Albert Einstein, the dude stuck moping the floors is literally Einstein. Allowing some normies into this society would free up more resources to be used more efficiently.
