Just to underscore what was previously stated, I think this philosophy would drastically change the paradigm. I’m guessing it would severely restrict the money flowing into stocks which would have repercussions in other areas like pensions etc. Point being, I don’t think it can just be layered onto the existing system without serious blowback.
But ultimately, it's supposed to change the paradigm. Because currently the economy is run by paperclip maximizers that no human is held responsible for. Which is not ideal.
