> The good point hidden in the article is that American culture has no real idea of "friendship" in a sense that people from other cultures either now or historically would recognize as such. American's just don't have friends. We have weak acquaintencnes. Why? Nobody seems to know. But it's something that probably deserves more attention.

I think that is a very interesting point. I have mentioned that as well in the past a couple of times. There was a difference in how friendships worked in my old country (in Eastern Europe) and how they work here. Here "friendships" are just acquaintances as you said. People gather lots of acquaintances but no or few good friends.

I'll propose a couple of reasons:

* People are more mobile. They move more so they don't have time to really make friends. This starts in childhood when kids move with the parents from school district to school district from neighborhood to neighborhood. There is a non-negligible network effect here and that is even if you don't move and live on one street and go to one school, chances are your friend's family will.

* Education system. At some point kids stop being in one class and are allowed to pick individual classes and schedules. So they stop seeing or spending time with the same classmates. There is extracurricular activities of course but it is not the same as starting with 1st grade and potentially being with the same group of people until the 12th grade.

* More individualism. Being a friend means sharing more and means relying on other more. In other words it means asking for help and offering help. This means "being in other people's business" which is a no-no in U.S. But the other side of being too individualistic means never really opening up to a friend. And at the end of the day one can only get so close talking about the weather, after some time it gets boring. So there is the wall that people don't let others through.

* Affluence. I think in countries where it is harder to survive on your own. People will stick together better for support. They have to have a support group to survive. In richer countries people can get by easier living alone and being more independent.

* It is not as much countries as times. In other words in the past, people used to have fewer but closer friends anywhere in the world. And, say, in the last 30 years people started to become more isolated. Could be technology, or globalization (people have to move because of jobs).

* It is not the world it is you. You just got older, more paranoid, and more withdrawn. The perception is that there just aren't that many friendly people around. But maybe other people just don't want to be friends with "you" in particular. They are still people with very good close friends but because you don't have them now, it seems like nobody does.
