> at the cost of the American worker/Graduate

The old myth of "immigrants are taking our jobs". The American economy (and all western countries) would be substantially weaker without all those immigrants, highly skilled or not. Without them, the agricultural sector would collapse, the health care system would barely hang by a thread, and next time you go use a toilet at your companies office or a random shopping mall, try to find out who cleans it regularly (hint: that person is most certainly not born in your country nor highly educated).

Immigrants grow the economy, if anything. They make your life better.

That I even have to read this nonsense in a place with so smart and highly educated people as HN makes me pretty sad.
