- So in the beginning there were people. And those people had problems (need for food, shelter,...).
- So to fix these problems more efficiently (but far from completely), people invented economies.
- But now these economies require infinite population growth (i doubt that's actually true).
- Therefore people make more people to sustain the economy. These new people themselves have needs, which did not exist before.
- So these new people now also need to make even more people to sustain the economy.
- Repeat.
So the economy actually amplifies suffering (exponentially), not reduce it.
Also, like others have pointed out: Many economies before industrial agriculture had basically 0 growth, and sustained themselves for centuries.
