The author of “Elite Overproduction Will Destroy a Nation” talks about the world and Japan in 2026 (Japanese)

Intro:

The theory advocates structural-demographic theory (SDT), which explains how large societies organized as nation-states periodically experience political instability due to polarization, social divisions, and institutional dysfunction. Rather than focusing on short-term events, the theory tracks deep structural pressures that build up over decades.

A 2010 paper in Nature used historical data and contemporary indicators for the US and Western Europe to assess these structural pressures and concluded that instability is likely to increase over the next decade, peaking in 2020.
