Ok, time foe UniqueMixture's theory of why politics/economics is not (nor ever can be) the answer.
Reason 1: human attribution of value does not come from cash it comes from dopamine release in conjunction with experience. $$$ does not take into account variance in the dopamine delivery systems that have evolved. This is why you cannot motivate some people with a "job" esp. low status ones that do not allow one to assert positive status. Also, some people don't release in conjunction with acquisition of possessions, this is why IN types are often not motivated!
Reason 2: politics comes from similar experiential feelings about life/the world/existence. The human race compels itself to acquire every experiential niche as a diversification strategy to survive. No political model allows this variance except one! That is the state of affairs in which coalitions of biomass vie with one another for territory and resources. If one coalition dominates another guess what? The new system will evolve the complexity of niches that it had before! Ideologues believe that everyone else is in their same niche : ) )
