trust emerges in situations with iterated interaction; defecting is most effective in anonymous or discrete situations, since there is less opportunity for punishment. america has urbanized rapidly in the last half century, at the same time that family formation has broken down and life-long jobs have become a thing of the past. we are atomized and thrust into constant competition. i don't mean to idealize a past that i did not even experience, but there is something to be said for having roots and knowing your neighbors. we arguably have more opportunity at the cost of stable identity -- reputation and trust naturally accrete around the kind of stability we lack. if you talk to older people, people around my grandparents' age or thereabouts, you will hear that they no longer recognize america, that it is fundamentally different than the culture they grew up in, in terms of values. i find myself thinking about this a lot.
