While this may have once been the case, there is scant evidence to suggest that modern societies consist of groups working towards a shared goal.
In early societies, members of a society might trade with members of another society to procure products that would benefit the collective. This fundamental economics supports the idea that, at one point, collective groups may have formed around the existence of a shared goal.
However, modern economic models show no evidence of a shared goal. The whole economic system has shifted from a model designed to offer protection and shared security, to one which speculates for the sake of speculation. The modern economic system promotes competition and encourages individuals to chase wealth at the expense of their counterparts.
In the postmodern world, we cannot define societies as collectives working towards a shared goal. In light of modern economic models, we can only reasonably conclude that societies are born from something other than a shared objective, or that societies, as they were originally devised, no longer exist.
