with functional immigration rules one can expect nicer people to be let in and bad people are forbidden to enter.

How do you propose we determine who will commit a crime before letting them in? Why do locals get a pass to you for committing the same crimes at similar rates as foreigners?

I think someone is misdirecting your anger to the wrong targets. Most immigrants do not want to harm you. Billionaires, on the other hand, love it when we harm each other instead of them. They don’t want to lose their wealth, their power; they want to widen the gap even more. They want to control us through fearmongering and deception.
