I felt the same way. Romanticizing hunter/gatherer society and downplaying positive effects of agrarian society or any notion of evolutionary psychology. It started OK and about halfway through it seemed like he was just giving thoughts and theories on various things, without any references.
Though more focused on cultural evolution, I much preferred Joseph Henrich's "The Secret of Our Success".
The only other book I read this year was Evicted by Matthew Desmond. It was an excellent account of poverty cycles as it relates to housing.
