There has been a cost to individualism no doubt. There are a few culutures where, generally, the community comes first.
I think you can cultivate that in a small way though, by taking part in volunteer programs in your community. I know it's a cliche recommendation but if you are feeling like we lack community then it's probably just because of how easy it is to separate yourself from it.
Elevating society above the individual stifles innovation and leads to stagnation.
The sensible model seems rather obvious: One has to organize their own show before one is of [much] use to others. Until that time one should give the others the opportunity to help you with that and be grateful. Its not an embarrassment if you plan to do the same.
