And what do you mean by first world areas not having a sense of sovereign? As far as I know, the US, european countries, canada, etc, haven't given up on their territory or submitted themselves directly to the will of a foreign power. The EU countries haven't given up on their sovereign either, they just agreed to work togheder, but a country can defect from it if it wishes to do so, there's nothing absolutely preventing it from doing that.
The number of countries where the leader is actually sovereign is dwindling. In plenty the King or whatnot is more for show and you certainly can't say any of the various politician groups have indisputable power since it's really all about limits. If Obama was sovereign losing the Massachusetts seat wouldn't matter and we'd have socialized medicine already
Of course Obama isn't the sovereign. The People is. More specifically, the people who actually vote are the sovereign. I don't remember exactly how the argument went, but didn't some philosopher ask, "If the king cannot choose his heir, who then has the power: The king, or the King Makers?" Okay, that is a paraphrase of what is probably a translation, but it contains the idea.
Also, did you never take a high school civics class that talked about "Popular Sovereignty?" It is very much present in the Republics of the western world. Other places, like north Korea or Cuba, not so much, though they tend to have some form of autocrat in power.
At any rate, a better question to ask with regards to defining civilizations would probably be whether they have a formal power structure or not? In Egypt, they had the pharoah, in rome they had the senate and later the emperors. During the Senatorial period, would you claim that the romans were not civilized? Okay, neither would I, but that is more because they were a blood thirsty people who delighted in murder and killing than because I feel like applying real anthropological principles to them.
