If you didn't want me to go into philosopher Tage mode, it's too late.
Perhaps its more of a cultural thing. Human beings are social 'creatures.' It has been proven, to function properly, we need connections with many other human beings. So, how do the two genders, traditionally, make those connections.
Traditionally, men were/are the breadwinners, and so they go to work where they are put in a setting with like minded, coworkers. They make their connections there. Easy.
Stay at home women, on the other hand, are forced to actively seek out their connections. Unless they are part of a church, or another social 'structure,' they do not have an easy answer.
Now, I know some of this traditional stuff is changing, but culture changes slowly. Perhaps we're seeing some of the remnants of this past circumstance.
Anyway, this is my thought.
