The video made me think of Peter Turchin's "End Times", a book that I recommend, for whatever it's worth, to you anonymous internet fellows. The book talks about many of the same arguments, and adds more. Its main thesis is that the author studied hundreds of major crises that led to war/poverty/revolutions etc., and the one thing all these events have in common is the excess of people that are willing to be part of the elite. He calls that the overproduction of elites: https://en.wikipedia.org/wiki/Elite_overproduction.
