Phrasing things as an optimization problem can result in better, more efficient arrangements than how things are presently, but only within the limits that people are willing to accept. It also depends what we're optimizing for - if we naively set it for "maximum number of humans fed and cared for", we really are all going to be eating bugs and living in pods.
Sounds like an instance of the No True Scotsman fallacy to me, friend. What is capitalism if not the systems that purport to be it? It's like saying "communism has never been tried". They tried _something_, and they certainly labelled it communism.
That said, I do find the Equity Fund idea interesting, though it's not entirely clear what this looks like in practice, especially for the unbanked, the mentally ill, homeless people, etc. who might not really know what to do with shares, since some of them don't really know what to do with cash, either. Seems to me these are the people most in need of uplift, no?
I'm not too worried about most lawyers getting automated out of a job anytime soon, after all, to the extent where I want to see the economy overturned for the likes of them.
Ah, fair. Yea, perhaps the capitalism we have tried is the closest that is practically possible.
I think we overweight how many people in society do not know what to do with cash. I think we may say that we believe they can do something better with it and sure perhaps, but it is bold to believe one knows what to do better with another's resources.
