SDT gives us understanding of the deep structural causes of socio-political instability and... tools for adopting... reforms and policy interventions that can reverse these drivers... It remains to be seen whether our society will be able to use these tools.

This is what I did in... Ages of Discord, I looked at more than 200 years of American history... an aggregated measure of well being... the blue curve has gone through two cycles, and the red curve is a measure of instability...

So far so good. But the problem is, as in many dynamical systems, there are some delayed effects of such dynamics. ...Here are some numbers on the relative distribution of wealth in the American population. You have good data from 1983 to 2019... when we look at the percentage of households with [inflation adjusted in 1995 US dollars] net worth exceeding... Millionaires, roughly 10% of the population (7% now) increased from 3% to 7% but then growth in... classes such as decamillionaires was even more remarkable... more than fivefold, sixfold increase in the proportion of households that have 10 million dollars wealth, or more.

[T]here are other dimensions. The state fragility and international environment, especially for smaller countries, international environment plays quite a role, but I will focus on the first two.
