Yes.
Yes yes yes yes and yes yes and yes. I cannot stop seeing waste and adversity. It's 2020 and nobody is really fearing anything critical but we still roam with our paranoia on it seems.
I assume (bedroom theory) that with some cooperation level we'd cut the effort of everything 50%.
I think human groups also need leaders otherwise they just don't see the whole picture and don't function well because everybody is trying to defend his cubicle.
ps: I don't know about kayfabe, maybe there's a bit in boxing, there's also paid matches .. I believe on average the competition is real enough.
The greater cooperation inside a tribe, the greater competition there is between tribe leaders. It's a fact of nature. You can't have one without the other.
I fail to follow, care to explain more please ?
I struggle with that two, and that's one of two big things. The other thing is: how so many things around us are balanced by adversarial relationships instead of cooperation. From nature, where ecosystem equilibrium is just a slow-moving frontline of life forms fighting and starving, to markets, where price determination relies on companies fighting over customers and ever pushing on each other. It's all so incredibly wasteful.
