TLDR: "The concept of “elite overproduction” has attracted a lot of attention in the past several years, and it’s not hard to see why. Most associated with Peter Turchin, a researcher who has attempted to develop models that describe and predict the flow of history, elite overproduction refers to periods during which societies generate more members of elite classes than the society can grant elite privileges. Turchin argues that these periods often produce social unrest, as the resentful elites jostle for the advantages to which they believe they’re entitled."
