Sure, some people want to get ahead just for the feeling that they're doing better than most people, but a lot of people try to get ahead out of fear of not having enough. In a system where everyone has enough wouldn't that fear be at least greatly diminished?
I think there is a pretty strong case that "having enough" is very much a moving target and now matter how much many people have it's not "enough". I see a lot of evidence that it's impossible to have a system where everyone has enough and I haven't seen a lot of evidence that it is possible to build such a system.
