What passes today as economic analysis is, in truth, modeling in which the assumptions and the data are implicit and only the conclusions are expressed. Moreover, projections are frequently based upon simple extrapolation of a constructed macroeconomic indicator and rather than exploring the underlying structure. It seems to me that "politics and power and sex and violence" and resource depletion,innovation, FUD, and all the rest is amenable to modeling and that a composite economic model based on systematic analysis is likely to better reflect reality than the process used now.
Asimov's Foundation Series books are enlightened works of science fiction, but they are fiction, not fact. I find is strange that you cite them as if they were seminal works in societal modeling.
I said Asimov "posited", which seems pretty clear to me. FWIW, Asimov has a certain cachet these days among some Keynesian economists.
When you are able to usefully, and predictively model "politics and power and sex and violence" then you will be doing extraordinary work and I'll look forward to you getting your well deserved Nobel Prize. :)
