Those in power want us to believe that current power structures were inevitable, that the world wants to return to the current mean should we try to change it. We just have to stop people from getting power over others. I think that this is best achieved through random selection of leadership.
That's true, and a good point, but this was much more pointed: less "had humanity evolved differently, we could have been nicer people" and more "what seems like the inevitably market- and capitalism-focussed way of life that's all anyone has ever experienced was actually a creation of the '60's and after." (Sort of like the current geopolitics of the US, which seem eternal to those of us, like me, who came of political age when they were already fairly well established, but which have actually changed dramatically in the mere 250-ish years the US has been around to have geopolitics.)
