1. So in the beginning there were people. And those people had problems (need for food, shelter,…).
2. So to fix these problems more efficiently (but far from completely), people invented economies.
3. But now these economies require infinite population growth (i doubt that’s actually true).
4. Therefore people make more people to sustain the economy. These new people themselves have needs, which did not exist before.
5. So these new people now also need to make even more people to sustain the economy.
6. 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.
