You have a more practical and perhaps more economic based view of the situation, which I don't disagree with at all. It's just that I'm a much more nihilistic person in my beliefs, I personally (and this is ONLY an opinion) believe that all humans are intrinsically horrible and evil to the core. I've never seen any iota of goodness in anyone. So I cannot simply see it as a matter of how we're nurtured by our society but as a fundamental part of the disease of human psychosis.
