“In the United States, 50-year instability spikes occurred around 1870, 1920 and 1970, so another could be due around 2020. We are also entering a dip in the so-called Kondratiev wave, which traces 40-60-year economic-growth cycles. This could mean that future recessions will be severe. In addition, the next decade will see a rapid growth in the number of people in their twenties, like the youth bulge that accompanied the turbulence of the 1960s and 1970s. All these cycles look set to peak in the years around 2020.”-Peter Turchin, “Political instability may be a contributor in the coming decade.” Nature 463, 608 (2010). https://doi.org/10.1038/463608a
“What does it mean for the current wave of protests and riots? The nature of such dynamical processes is such that it can subside tomorrow, or escalate; either outcome is possible. A spark landing even in abundant fuel can either go out, or grow to a conflagration.
What is much more certain is that the deep structural drivers for instability continue to operate unabated. Worse, the Covid-19 pandemic exacerbated several of these instability drivers. This means that even after the current wave of indignation, caused by the killing of George Floyd, subsides, there will be other triggers that will continue to spark more fires—as long as the structural forces, undermining the stability of our society, continue to provide abundant fuel for them.-Peter Turchin, “2020.” Clio Dynamica on PeterTurchin.com.
