Thanks for that video. Very interesting, very interesting indeed. I watched another video where they made the connection between inequitable societies and social ills. This video just backs that connection up.
That's super cool. Sense of unfairness to equal effort/opportunity. Combined with the natural cooperation studies puts paid to the notion of the possibility that society could comprise nothing but totally selfish, uncaring individuals. Division of labour and trade would never happen in the first place. Just because someone can dream it and make a movie/story about it, doesn't mean it'll ever happen.
