It's pretty lengthy indeed. However I believe the root grows over this "…And just like the last epidemic we lived through, the trauma appears to be concentrated among men." and women liberation has to do with it as well. In the sense of how they began to life towards fields unreachable to before, breaking their constrains, while men keep on living in pretty similar roles from fifty years ago, male roles transformation or liberation hasn't seen such radical changes as the females one and the world appears to be focused on fem equality, what leads to the masculine view to be secondary.
Regardless, both parts faces the search for happiness dilemma, which women can fulfill it better than men achieving things that they haven't before, but what can men do that they haven't done so? There lays the emotional awareness of themselves, sociability in an alienating world -perhaps a cause the technology or the current political state of it- remains as a difficulty to men. Sure most can start a conversation but not bond to the level that women do -and fight over it, of course- and that reflects on their growing loneliness and feeling of emptiness.
