I don't think there was a point where all humans were wondering about thinking ''oh isn't life hard on my own; i think i'll join some others to improve my quality of life''
Humans were together FROM THE START
This means we must see the concept of an almost group mind existing overlaying the minds of individuals
It wasn't that people got together out of self interest, they were intimately linked together from the get go...seperation is an abheration
Even today where we are encouraged to be as seperate as possible, by a sick culture, we are NOT seperate but completely inter-reliant and inter-linked
Science is now beginning to rethink the idea that consciousness is created by the brain. So if consciousness is external and flowing through us then we can really think in terms of an interconnected consciousness

How happy do humans who follow the capitalist idea of selfish self interest seem to you? Sure it works for psychopaths because they don't feel the same way as regular folks do but regular folks are social animals
Its not that they choose to work together it is that they evolved to work together...they're one unit
Chomsky speaks about how many people missinterpret the work of Adam Smith and about what Smith really meant was that he expected people to work together with their immediate national community rather than communities elsewhere in the globe ( a 'home bias')
