> Bad immigration policy can and does negatively affect opportunities and salaries.
It is true by definition that some immigration policies are worse than others — for example, a policy of no immigration at all (which is a kind of immigration policy) would be very bad for opportunities and salaries.
Do you think Elon Musk (and every other foreigner who founded US company) diluted supply of labor, or expanded supply of jobs ???
For ex Microsoft was a failing company and losing market share under white american Steve Ballmer, reaching $230 bln market cap.
It took an Indian ceo to make microsoft a two trillion dollar company, there countless examples like these. I am not even talking about how fundamental research by foreigners gets converted into billions of dollars of gdp and market value (and jobs ofc).
The argument that foreigners “steal” jobs is fundamentally flawed and is coming from ignorance/bigotry
