You know, I've been thinking aout this one recently. Even though humans have moved on from that hunter-gatherer paradigm, if we look at how things are going, considering a lot of nations make a living by war profiteering, aren't we still in a way under that same paradigm? The money that nations get still end up being the backbone of the economy where goods and food are traded on.
Yes, people still set traps to catch their prey, only now they do it for money and with words. I mean those weapon (and other stuff) traders use words to sell what they sell (whether they blackmail to achieve this is another thing), money goes to whom it goes. I'm not sure if it is distributed into the society.
So, it's not to feed oneself and immediate fellow beings, but to amass wealth that money can provide. Not many seem to think further than that. We can't breath money, we can't drink money and we can't eat money, do we? Will humankind ever embrace the idea of peaceful warrior/warrioress who does not go about attacking, and then punishing and/or rewarding before humankind gets extinct? Imagine to squads meet somewhere to battle and they just sit down and say, "Oh, who cares what the commanders want, let's just have a picnic."
