Man, more people should read Schumpeter. Capitalism is really good for rapid growth. The second the profit motive negatively affects the quality of the product or efficiency of its production a company should be nationalized to prevent the profit motive from destroying part of our economy (the actually-useful part, that is, not investors or shareholders or dividends).

Technology ironically. The stuff Peter talks about where Y=0. The covid vaccine inventors for example.

Other Y=0 things are people giving their lives for the greater good and basic rights. Geneva convention. Rights for black people, rights for women.

Infact the world runs on Y=0 stuff.
