I can't help but be pessimistic about that diagnosis (which I think is entirely correct, by the way). Democracy is a perfect example- as Churchill said, it sucks, but it's the best we've got. Will we ever be able to create a perfect replacement- for religion, for capitalism, for anything?
And I agree wholeheartedly with the growth obsession; I think it's that very attitude which is distracting us from true progress (whatever that may be). I tend to think of Apple: the richest company in the world, and yet, because they have shareholders to answer to, even that's not enough. There must always be more.
