Man, that's a tight world you see.
Reciprocal and non-heirarchical social structures may not exist now in larger portions of the civilizations that inhabit the earth now, but they do exist. And I still disagree that it is hard code for us to gravitate to forced control.
Yes, I agree, 'we' live in such a crappy construct, but that's not to say it doesn't have to be that way and I think you discount the ability for humans to naturally want peaceful co-existence overall.
take a look at your own neighbourhood. you don't all live in the same house, you don't all follow your community leader, but you do want your street lights on and you do want your garbage picked up. In that sense, there is reciprocity more than leaders and so on. I think that political mantels are donned, but for the most part of the year, unneccessary.
Maybe it's the libertarian in me more than an ideal. A social contract and construct can exist with a reciprocal and egalitarian society.
yes, certain people will be asked or will work towards management and maintenance of infrastructure, trade and even the military if need be. But decisions that effect life or death should not be in anyones hands but their own.
true democracy works towards this end. all service to the whole that is in agreement is voluntary, those who can't abide don't have to, but are not included in the resiprocity of the society.
I know where you're coming from, but you gotta see the possibilities. It's not all bleak house.
