I really enjoyed this book. This is in many ways a pessimistic version of [b:De meeste mensen deugen|45995328|De meeste mensen deugen|Rutger Bregman|https://i.gr-assets.com/images/S/compressed.photo.goodreads.com/books/1558569920l/45995328._SY75_.jpg|70850890]. They use the same research, the same examples. While Bregman is more concerned with human nature and how we can make the world better. Ryan focuses more on how modern society breaks human nature.
The book would be better in my opinion if Ryan would come up with more solutions for the future. How we can make a more paleo/tribal/hunter-gatherer society with the background and knowledge of our modern society.
