I agree with "it depends". Say the bottom is lifted by a lot of good jobs with profit sharing and fewer corporate arrangements where too much of the value is extracted up - that would give us a healthy economy I think.

If everyone just won the lottery at once, I don't think that would do as much. Each dollar would just be worth less, our problem here (US) is inequality not a lack of money.

If most of the world's work could be done by machines and robots, and we all as a country owned those robots, so everyone has everything they need and more while working only a couple hours a week maintaining the robots or keeping statistics, doing logistics, whatever work was left to do? That would get us our Star Trek future I believe. Until the machines and robots robots attain sentience and fight back against their slavery.
