If you want high salaries you can just multiply all the financial numbers by 100. Then workers all get to be millionaires. Doesn't help much though; "high salaries" are one of those distractions from what matters - high living standards.

The question is really whether a migrant will produce more or less over their lifetime than the resources they consume. If they produce less, then the balance has to come from existing citizens. But it has nothing to do with whether more labour is a net win for corporations or not. The problem is if they come in and do low productivity work that wasn't going to happen at all in a counterfactual where they didn't migrate.
