My understanding of your post is that you think the US doesn't need more skilled immigrant workers because those jobs should go to Americans first. That's a valid argument. Attracting skilled immigrants indeed have both cost (i.e. Americans don't get those jobs) and benefit (i.e. America get the best workers and become more productive). I think the benefit outweigh the cost, and you vice versa. That's another debate entirely, which I'm not pursuing here, but I do want to recognize the validity of your argument.

The original post I made, on the other hand, is not about whether the US should attract skilled immigrants. I just wanted to clarify that the US does NOT have a generous immigrant system for skilled workers, contrary to popular perception.
