The US's strength is/was in part because of immigration. The best and brightest want to come to the US to go to school and then they often stay for the enormous opportunities only available in the US. I want any immigrant that wants to come to the US given a reasonable path to make that happen.

You are right that the Native Americans were completely misplaced by immigrants, but immigration made the US what it is today and I see no reason it won't continue to make the US a uniquely strong country.

It’s sad that pragmatically adjusting quotas is never the loudest argument in the room. I’m in favor of greatly increasing legal immigration, providing paths for safe work and citizenship (when that’s the goal). I’ll admit that my idea of an ideal system is probably not palatable for many. But if we could start from anywhere near a sane baseline, I’d understand wanting to gradually find sustainable quotas that take all factors into account. I’m done with purity tests and letting perfect be the enemy of good.

I suppose by “all factors” I mean all factors aside from exploitation and xenophobia, but I hope we could at least move the Overton window back that far.

The citizenry would probably fare no worse than with the arrival of the Irish, the Italians, or the Germans. What are you expecting, for the Indians or Chinese to sack DC aux Visigoths?

“Open borders” was pretty much standard across the world prior to World War 1. These tightly controlled immigration policies are, historically speaking, incredibly new.

I think it’s self evident that the U.S. benefited greatly from its mass immigration inflows in the 19th and 20th centuries.

Are you serious?

"Oh, you support immigration? Write an entire nation's immigration policy. Can't/won't do it? You must be a paid shill."

People are allowed to have opinions without regurgitating policy documents on demand.
