Peter Turchin, a scientist who applies mathematical models to historical change, uses his framework to explain America's current crisis. In 2010, Turchin predicted that social disintegration would produce a breakdown around 2020, driven by two dynamics he calls 'elite overproduction' and 'popular immiseration.' Elite overproduction occurs when a society produces more aspiring elites than it can accommodate, creating frustrated strivers who destabilize the system. Popular immiseration is the declining well-being of ordinary people despite economic growth. Turchin finds these dynamics in historical collapses from Rome to the French Revolution, and identifies them in contemporary America. The book combines quantitative analysis with historical narrative, showing how structural forces produce the cultural and political symptoms we observe. Turchin's approach is controversial; critics question whether human societies can be modeled mathematically. But his predictions have been accurate enough to command attention. For readers seeking explanations for American dysfunction, Turchin offers a structural analysis that goes beyond personalities and parties to examine the underlying forces that shape political possibility.
