Yeah thats noted about 10 times in the comments immediately below the video. Apparently its the only thing anyone knows about him...or the 1st google result. Apparently he made that comment in a book he wrote in 2004.  Wonder what kind of statements you or I would have made in a book IF we wrote one (of several) and it was published 20 plus years ago?  Regardless,  this is the 1st I have ever heard of him.  He clearly has a lot of knowledge regarding China though, he speaks at length for over an hour and has countless statistics etc.  I can't attest to the guest being an expert though.
The show however, is brilliant.  In regards to your snark about Leftist indoctrination,  if you dont think current academia indoctrinates people with Leftist notions then thats a "you problem" .   Most Universities and especially the ones formerly considered the best like the Ivy League schools are made up primarily of professors whose political views are somewhere Left of Lenin. They turn out these brilliant baristas and politicians hellbent on making this country another failed Socialist state.  The Hoover Institution in contrast is made up of folks like Sowell and Hanson, who managed to graduate from Harvard and Stanford, become tenured professors there as well...but not be deluded into believing the terrible failed ideas the Left keeps recycling over and over in this country.
