I'm buying into his thesis, but heck, I really expected to see some causality explained. The title began, after all, with "how did...." It would be great if somebody could provided an insider's account of why the academic publishing industry maintained those margins from 2000 to 2010. Did nobody propose legislation to stop them? Were there no criminal investigations? Who are these people connected with politically? What sorts of causes to they contribute to? Just how is the status quo maintained? The guy made a point I was already predisposed to agree with, then kind of went on a rant about how bad it all was. Hey, I'm with you. I'm just not sure my useful knowledge of the issue has increased any.
