Here. I don't have time to provide thoughts in detail but you can probably anticipate them.
He makes the case against labor protectionism: good.
He makes the case for high skill favoritism: bad.
He disputes some things from Dean Baker: I'll leave that one to Dean, who suggests he'll write more.
I am neck-deep in these issues right now, working on a briefing paper that hopefully you'll hear more about in the coming weeks (this ought to be quicker than the process at Urban, I think). Needless to say, the more I learn about the existing high skill programs the more I dislike them (which is not to say that I dislike high skill immigration).
My dream policy is a relatively open system with a guestworker and permanent component (with strong family-based provisions), with no picking and choosing on the guestworker side of which types of guestworkers we prefer, full portability of guestworker visas.
In the absence of that dream policy there is a lot to clean up in treatment of undocumented residents and a whole lot to clean up in high skill guestworker programs.
First and foremost I'm interested in the economics of these questions and not the politics (just because that's my area not because I think the politics are unimportant), and so I truly bristle at invocations of labor shortages to justify high skill visas.
