Immigrants do bring important social and cultural capital. But nobody here is arguing in favor of no immigration.

The standard among countries all over the world is to regulate the flow of immigration via immigration law and deportation of people who violate that law.

How could a massive influx of people happening faster than a system can react not strain the system? I saw this firsthand in schools and hospitals where I grew up, and there are numerous examples throughout history from around the world of the disruption it can cause.

The US is not like many countries in that it was formed by illegal immigrants, and not just immigration, literal genocide and land theft of the indigenous people.

That being said, all immigration policy is out of date. The world is connected now and the policies are an anachronism.

I don't agree that this is reality. Our system is not under strain from immigration. It's under strain because we spend our money on the military instead of improving infrastructure. It's also under strain due to wealth inequality and corporate friendly policy. None of which has anything to do with immigration.
