Matloff has grown on me over time. He is a math PhD and a computer science professor, so I had a lot of trouble at first with how he framed and thought about things, but making an adjustment for that difference of perspectives I've appreciated him more (not that I concede his is always the best way of approaching a question).
Haven't read this briefing paper yet, but it looks like it's similar to things of his I have read and talks I've seen him give. Peoples' sense of the composition of the high skill immigrant population is often skewed and he addresses some of those questions.
