I've wondered recently if historical prominence and quality of life are anticorrelated: if the civilizations we think of as biggest and greatest are the ones that were the worst to live under. Or, more provocatively, if civilization is just relationship dysfunction on a grand scale.
What is civilization? It's centralization of power, increasing specialization of roles, usually higher population density, greater interconnectedness between people, a dominant ideology & discourse, and subordination of individual will to collective power. We look at the Romans or the Mongols or the Aztecs or the Pax Britannia or Pax Americana as great civilizations because there is something there that us, as observers centuries later, can point to and hang our minds on.
But what does life look like for individual humans under one of these civilizations? The Romans practiced slavery on a grand scale; the Mongols conquest, the Aztecs human sacrifice; the British colonialism; and the Americans capitalist exploitation.
There is a movement, today, that life should be more focused around local communities, person-to-person interactions, individual freedom, authenticity, and a return to human-centric ideologies. What would such a society look like to future historiographers? Communications would revert to person-to-person interactions rather than massively published tracts. Much of it would be ephemeral; Snapchat or Whatsapp rather than the WWW or Twitter. There's no need to fix communications into a tangible medium or distribute it widely when the audience is a single human being at a single moment in time. Large infrastructure projects would essentially become impossible, as getting the required cooperation from different interests without a monopoly on coercion becomes unrealistic. Think of NIMBYism on a society-wide scale. Trade might continue, but rather than organized supply-chains, it reverts back to supplying individual wants.
To an observer a millenia in the future, it would look like a collapse of civilization, because there would be no big entities that they could look at and say "That's how people lived back then." But to the individual human living in the moment, it could instead be viewed as a return to freedom, community, and person-to-person relationships, all of which are valued highly by nearly everyone (particularly today). Both viewpoints are true; the difference is in the scale that the observer observes them.
