The simple fact is no one really cares about the plight of men, and this is obvious when you look at social service funding and especially homeless shelters.

We are in a 'bare branch' crisis, and back when this happened in medieval China, whole gangs of angry unmarriable men would form raider bands and just pillage and rape until they were put down by the military. It happened so often that warring states would purposely stage useless battles with massive losses on both sides to keep down the 'bare branch' population so they didn't get to rioting levels.

Maybe the fact that warfare is no longer culling the most desperate, lonely, and impressionable men has let to such a large population of unfocused, angry, lonely, and fundamentally unlikeable males.

It's mainly because biologically we evolved to have kids and die on a hunt, our evolution pressures just aren't capable of handling a male population without a certain degree of unnatural casualty.
