One thing I've noticed: he is using the number of PhD students as an argument that people need more and more elite credentials to achieve anything. I am not impressed by this part of his hypothesis, since the academic machine simply uses naivety of young people for slave-like, tedious academic work. Especially in US, many of them are foreigners and will leave the country afterwards at some point, as far as I remember. It has a lot to do with how academia is structured (you have to get a PhD if you even consider a career in science) and not with any practical advantages it gets you.
