The Fourth Turning Is Here:

This book lays out the theory that anglo-american history has moved in cycles since the 1500s, following roughly 84-100 year (a long human lifetime) periods. They also propose that the 4 generations involved follow rough cycles as well (Prophet, Nomad, Hero, Artist) that are reactionary to what's come before, not engrained in the people or through some kind of mystic reason. He lays out a lot of anecdotal evidence to support the theory. Like most theories that look at historical data for a pattern, I think there's a bit of squinting to fit the archetypes proposed and the seasons of the cycle that are laid out in the theory. I also question what we can do about this, even if it's right. There is mention at the end that if we know winter is coming we can act like it but I'm not sure that is meaningful if you say that you have no idea the shape of the coming crisis will take.

Anyways, the author hedges to have the crisis ending sometime in the next decade. Good luck everyone.
