I made it the fuck up as a ballpark because I forgot the exact figure but the simple answer is that the western masculine and feminine social roles that he constantly gestures towards were invented to serve the interests of the elite land/private-property owning class as western powers moved away from feudalism towards mercantile capitalism and eventually the industrial revolution and imperialist global conquest.

The men go to work and have the surplus value they generate for the boss stolen while women stay at home and perform all the maintenance labor for free (such as taking care of the kids). This was the social model pushed on the masses by the elites because it ensured smooth operation of a system where they benefited the most.

He attributes real social problems like expensive cost of living/nonexistant employee bargaining power/social malaise due to the systems we use to relate to each other being fundamentally antagonistic and anti-human solely to a mystical individualist problem (a crisis of initiation), an interesting theory but a gross oversimplification of reality.
