Proof?
I'll take a stab at this one:
Talk to a few anthropologists (I have, obviously or I wouldn't bring them up) and look at the "evolution" of human civilization from Hunter-gatherer in the caves to our present day society. Two characteristics of our societal development have been key to our success, as opposed to say, Neanderthals.
- Centralization of Leadership
- Specialization of Tasks within a communal group
BTW, the former led to the later.
This isn't that hard to see: look at your favorite
Completely Private, Voluntary organization. Someone's "in Charge." Always. Maybe "some people" are in charge, but there is always a clear chain of authority. With private institutions, this chain of authority is voluntary; you don't like the company or the decisions of the chain of authority, you find yourself a different place to work. Currrently with our coercive governments, (the "state" for those who want to not sully the word "government"), you don't have that choice unless you wish to expatriate yourself from the country.
Also, if it weren't for item 2, then we would all still be "hunter gatherers" or "Jack of all trades, masters of none." It was this development in our social behaviors ("Okay, I'm gonna do nothing but make the arrow-heads, and you're going to do nothing but hunt the meat while Betty and Wilma do nothing but make our clothes..."), that anthropologists observed a drastic increase in the sophistication and quality of the things that particular group produced.
...and again we see this today. Not everyone is a car mechanic, or a programmer or a chef. Our social behaviorism's have required us to specialize in a particular task within our social community. There are those who are "masters of more" and they generally are paid more or rewarded, and there are those that are still "masters of none" and they tend to end up digging ditches... or throwing back to my pre-historic reference...scavenging the mammoth found dead a half day's walk from the tribal villiage.
So yes, centralization of leadership (amongst the one or many) is required. The real question is, "does that centralization of leadership have to be forced, or will human beings recognize it's 'survival/efficiency benefit' on their own and come to the conclusion naturally?"[/list]
