That's helpful. I'm curious to know of a system (like democracy) that is/was enjoyed by its people and if so, it's a success IMO. I incline to the view that democracy is the best form of government, although I cannot corroborate my own statement because my knowledge of politics is poor.
I have a similar inclination, though I strongly suspect a cultural and familiarity bias. I've been trying to go through the literature of political philosophy and dynamics, which is ... complicated. As with economics, a key point to remember is that virtually everyone writing on the topic (and most especially those who've been promoted to cultural consciousness) are promoting a model that benefits ... someone.
I've found William Ophuls to be an interesting point of entry. His topic is politics within a context of ecological limits, but he has classic training (he's strongly influenced by Plato), direct experience (positions in the US foreign service), and an excellent grasp on modern (mostly 20th & 21st century) thought on ecology, limits, and the interactions of these with polity. His bibliographies are excellent, and worth publishing on their own right. I'd recommend his 1977 Ecology and the Politics of Scarcity and his more recent Plato's Revenge. The former focuses more on the ecological case, the latter more on the questions (with very few answers suggested -- he's really exploring the problem space) of how you'd construct a polity, given environmental, psychological, and social limits.
I'm also starting to form some new thoughts on the role of religion as something of a social glue in vast empires over which communications might take weeks, months, or years, but in which a plausibly predictable level of trust would be found. Religion-as-trust-glue strikes me as a fundamental aspect. Curiously, instantaneous communications (and the monitoring and management that entails) allows for a near-total breakdown in such trust.
