That is all policies and political structures are testable and tested to see their effect on those three (or other suggested) factors. If a policy doesn’t reasonably work then it’s simply not continually employed. I’m curious to see what factors others think ought to be used.
It seems most political systems now were built without science in mind and utilize it as an afterthought to help develop legitimacy for policies individuals want. Generally politics across countries seems deeply emotionally driven and not fact driven. That is people have a feeling that an idea is a good idea and then they cobble together whatever they can to support that point without any unified measure of good or better. Ideally it ought to be the other way around, fact or evidence informed policy generation.
Oh that is already being done its just that human wellbeing isn’t the goal and the process of efficient management isn’t public facing
Yes although we don’t really play around with political structures that much. They may as well be infallible religious doctrine. Also most definitely the goal currently isn’t developing the best society.
