Who is the "our" here? My identified in-group is rootless cosmopolitans, so I am happy to see globalists of any nationality take jobs away from protectionist xenophobes.
Do you recognize that your in-group is not widely represented? It's not xenophobia, you're trying to dog whistle something about my character that is untrue. Can you acknowledge that you're being protectionist of your privileged class?
You're suggesting that we should erect artificial barriers to prevent certain groups from accessing lucrative jobs to protect certain privileged classes from competition. It's morally equivalent to (although more socially acceptable than), e.g., banning the hiring of non-white people or women so that white males can make more money. If you can discriminate on the basis of nationality then why not race and gender and religion also?
