Maybe we're creatures that are very well adapted to walking down a prairy in the company of a small group of friends (which is why it's recommended and usually feels good), a little bit adapted to farming and cattle-raising in a small village, and not at all adapted to abstractly producing wealth in a giant city... Unfortunately, we're probably not going to become adapted to that, because we keep throwing new challenges at ourselves at an unsustainable rate... Oh, hey, people are going to get confused about my username again, I guess.
