How about we take away everything down to 10^6$ from the 0.0001% richest and redistribute it to everyone. We repeat this with the 0.0001% of the richest every year from there on. Every time someone is chosen for this honour they get a medal.
Imagine for a moment you are a driven, self-made .00001%er. If you KNEW your profits were taken at the top, would you work hard and innovate? Or would you commit fraud and squirrel away your wealth or not bother. Im sure a few would see it as a 'goal', but stakeholders would doubtlessly disagree. The spirit, I agree with, but not possible to cleanly implement.
Lots of innovation for example Congress it of universities, from people who are not millionaires.
