Yeah, we already do that. There is no need to change anything. The system works. More Americans commit crimes than immigrants do. There have been plenty of white school shooters, but we haven't banned guns yet have we?
Diversity is our strength. I believe that all people are born good and naturally want to help and work with one another. When you put two babies of different ethnicities in the same room they play together. Racism is taught. Acceptance and tolerance is ingrained.
To those who desperately need to come here. We should start with those who have been the victims of US imperialism in the Middle East. We destabilized their region and we owe them a stable country.
People who don't need to come here, like white Europeans, should be limited from entering. They have their own stable countries to live in. Many do not because the US abused them.
If our capitalist imperial conquests destabilized regions inhabited by whites, then I would say they need to come here too. The fact is, we only exploit countries where PoCs are the majority. That's a fact.
