If that's the case, could we develop methods to ensure that communities we build have inclusion mechanisms to ensure all people (including mentally ill) participate and are valued? Sometimes I wonder if hyper-individualism in western society plays a big part in mental issues, since it is so easy to isolate oneself from any community. It is left up to the individual to find communities, there is no mechanism to stop people 'falling through the cracks' like there would be in a tribal community or even modern close-knit villages / country towns. I don't see how social life is a zero-sum game. Sure, some people gain status and popularity above others, but that does not preclude inclusion of all people. I.e just because Bob has 10 friends and Alice only has 2, doesn't mean that Alice can't be part of Bob's community.
