That doesn’t seem right. You would just not have any immigrants at all, because full employment is not possible, and many companies will move elsewhere or shutdown if they cannot get the right talent here. And then people will wonder why there are so few employers. Running a business is already very difficult and risky. It just wouldn’t be worth it for many employers.

Also the reality is that a lot of American workers are simply not employable in the industry they want to be in. It’s not a question of cost - H1B visa workers are paid slightly more on average. The most important American companies - like big tech - pay immigrant workers the same as anyone else.

And to be honest I don’t think training is an issue. For example there are thousands of unemployed engineers who have a degree - but still aren’t fundamentally skilled enough for most companies to want to hire them. Many of those people are blaming immigrants for their unemployment but I don’t think they’re correct.

I do agree that it’s ideal to support the current residents. But I just don’t think it’s realistic to see every single one of them employed in the best jobs. Maybe the best we can do is improve our investments in education?
