It's an interview that covers many topics. He doesn't have time to fully qualify every statement. Frankly, doing so just to satisfy the critics would be a waste of time that he could spend building his companies.

A good rule of thumb is to try to be charitable when evaluating a piece content, unless you have a good reason not to be.

I'll bet he has plenty of respect for the "poor losers" but little for those who took advantage of them (PhD programs).

If that's the thing, then I am with it.
