...until they misuse that one too? I have a feeling whatever is established leads to those in charge fearing it would stop eventually, so they start imposing all those strict rules. Like in 1984 book where they say the goal is to just keep the system the way it is, that's why they make all the exaggerated efforts. I guess we can't have perfection, or at least not a collective one, because...it will be like that when you're human. Even if it can be achieved, it apparently takes a lot of time, the governmet in Divergent tried to do it faster artificially and that didn't work. Maybe the point is that flaws are really exaggerated virtues; maybe if we want to get rid of a flaw we need to tone it down until it becomes a virtue (which is done by mixing it with other virtues). Maybe the factions also failed because their ideologies were centered around how to stop what they hate rather than how to increase what they love.
About democracy, the problem is also, as I heard once, that 'two people who are wrong have more rights than one person who is right'. Not to mention there isn't a 100% true method to only exclude those who shouldn't be allowed to vote, no matter what limitations you set there will always be those who are allowed but still wrong and vice versa. There's just not such an universal way to figure who really knows what they're doing...this is why I hate society and love people.
