It sort of can! Think about a very-religious church group or a military squad. When people are forced to spend all their time with a small group, they mostly become friends.
I'd hardly say that a religious group or the military could be classified as a society, they're just organizations within a society. No one is depriving these people from joining the same organizations today
the not-very-distant past, we lived in much smaller communities with much more interdependence.
Again, no one is stopping anyone from joining a commune or a village. And even within the organizations and social groups you mentioned there have always been social outcasts.
a lot of boys have not been raised to develop the skills they need for this new society.
I would say there is some truth to that, but at a certain amount of one recognizes that about themse there is a onus of personal responsibility required if you want to make changes.
