Of course, 'libertarians' like RW and others think we need more third world immigration. I would love to see Trump squash the H-1 program and limit green cards. I'm doubtful of these companies need for outside talent. Given the crappy wages and such and competition with foreigners, why would any parent recommend a STEM degree to their child?I don't "think" we need more immigration of any kind. My view is let the markets decide. If employers want to hire immigrants I have no problem with that. Why should I get in the middle of a mutually agreed upon exchange?
If employers want to hire immigrants, there must be a reason. Most likely they are willing to work at a cheaper price, that is, they will work for less than current Americans will with the same skill set. If Americans aren't willing to compete with foreigners at the lower wage, it means they have better alternatives.
This is how free markets work. Capital and labor are directed toward the most useful functions.
