The thoughtful Adam Ozimek thinks that isn't enough.
He thinks the United States needs more high-skill immigrants. I think the United States needs more immigrants--more people willing to take risks and work hard to seek a better life for themselves and their children, and illiterates from Chiapas seem to me as good as doctors from Calcutta"
This is a point I've been making a lot for the last several months. There's very little evidence of persistent high-skill labor shortages. That's what we have wages for. There's no reason to privelege this class of labor. None of the people who talk like this would make statements like this about priveleging certain types of imports over other types. So why do they do that with labor?
Never mind the fact that immigration is about more than just the labor market: people have aspirations to be Americans besides just high skill workers. My family wouldn't have made the cut if we had focused on high skill workers in previous centuries.
A note in light of some recent unpleasantness: this is one question where Don Boudreaux has always been very clear and very right. Even when some of his colleagues came out in support of "staple act" legislation to make it easier for high skill workers to immigrate than low skill workers, Don said quite clearly that there's no reason for extending such special priveleges. You can use the search function on the blog to find specific instances - I know I drew attention to his posts on that in at least one or two cases.
