I find very little to disagree with in what you say. All I ask for is a presumption in favor of allowing a willing foreigner to work for a willing employer. And I think that small harms like reduction in wages from say 100k/year to 60k/year is not sufficient to override that presumption especially since for the foreigner, the opportunity to work in the US often translates to a 5-fold increase in their income.
