>If you let in people with the skills you want isn’t it mutually beneficial?
No. If a person can decide for themselves what they want (what benefits them), then I decide that I do not what that, and it is therefor not mutually beneficial. If you have some alternate theory of objective benefice, I'll hear it, but it seems you only assume such exists.
I don’t understand you. If a government decides it wants a particular type of worker (eg a nurse), then it can give them residency, a work visa or something like that.
What’s the issue? America appears to be on a different path.
