His new book is called End Times but it does not appear to be about the apocalypse, but about a cyclical view of political history with some evidence to back it up.

When a state, such as the United States, has stagnating or declining real wages, a growing gap between rich and poor, overproduction of young graduates with advanced degrees, declining public trust, and exploding public debt, these seemingly disparate social indicators are actually related to each other dynamically. Historically, such developments have served as leading indicators of looming political instability. In the United States, all of these factors started to turn in an ominous direction in the 1970s. The data pointed to the years around 2020 when the confluence of these trends was expected to trigger a spike in political instability.

I haven’t read the book, but I have officially added it to my queue of too-many-books-to-read-before-I die. (I’m not terminally ill that I know of, it’s just a long and growing list.) The queue is periodically randomized, so just because it already has too many books to read before I die does not mean I will never read this particular book.

Anyway, one disturbing implication just from the brief description above is that we may not be able to educate our society out of economic inequality. That seems to go against the data which clearly show that people with more education earn more than people with less education. So it’s a case where a dynamic model leads to a different, counterintuitive conclusion compared to a linear extrapolation of data from the recent past.
