3/ Anyway. If we remove ideological doctrines that are extrapolated from simplistic economic models. What is left?
A system of systems of systems etc. A real global economy. Hundreds of slightly or massively different national economies, which break down across all sorts of things like sector, geography, class, whatever. Down to the individual.
But also a system that has at least partially been created by these economics ideologies. Which means that it has clear features from them. On all scales.
