You mean the western world? The rest of the planet live with/on very little.
This is about living well without living wastefully. Too much of the world believes we can either live in poverty or ruin the biosphere for future generations.
If you make no effort to both live well and live within a reasonable footprint, it shouldn't be surprising when you fail to achieve both goals.
the west is definitely wrong however, as there are wealthy nations all over the world
All humans, even those for whom that would be a huge step up, not just those who might currently think of it as some kind of virtuous personal sacrifice.
I would like to see a world where The Haves are not obscenely wasteful, The Have Nots are not screwed by a system that makes it impossible to find some means to get your needs met on a budget and the middle class is not being exterminated by our social practices, policies, etc.
I'm too old to believe in faerie tale endings, so I'm not holding my breath here and waiting for anyone else to agree with me. But I'm also old enough to speak my mind anyway and say exactly what I mean rather than what I think other people will find palatable or expect based on their current mental models and world view.
