Western culture is saddled as "evil consumers" but get real - if Africa or Madagascar had access to big box stores they would be buying blenders too. It is an innate human trait to collect items and build the biggest and best 'nest' possible. Impressing other humans and advancing in prestige general rests on this display of 'stuff' - general misery is applied to having less stuff. Indeed when we look at "how bad things are" in 3rd world countries it is usually couched in the language of, "those poor bastards have less stuff" - - possibly because in the first world we really don't 'get' going hungry.
Oddly enough although the drive for sex and food is widely recognized and discussed I've not really seen anything actively address the need for such oddly over the top nest building and nest tending. We're just like bower birds really - here in the US your nest means a great deal about who you are as a person. We expect movie stars to have amazing nests. Often people will have such big and elaborate nests that they cannot use every room or all their stuff in a single day.
How do we get people over the need for such expansive nest building? The only way to conquer an action is to replace it with a new one.
My personal idea is to extend communities and have a wealth sharing. So that my community has shared bicycles, shared recreational type items and the pride of 'home' becomes pride of neighborhood.
That's just my idea though -- I want to hear yours!
