They were invaded. But, thats irrelevent. Their societies worked. Only, each was eventually eclipsed by more militarily powerful countries. We don't live in an age where countries being toppled by more militarily powerful countries is the norm. But again, thats irrelevent. I'm not saying they were better cultures and societies, I'm just saying they had a point when they said that maybe government's purpose should be to help the people lead as best lives as possible.

Furthermore, such an idea was not based on something that can be proven. I mean, when you think about it, where exactly do we get these rights? We all say that we naturally have them, but whose to say that we dont? Where is it written that we have the the right to freedom naturally. I mean, there are many things that I could say we have a natural right for, but everyone would excuse it as baloney. But, when it comes to life, liberty, and the pursuit of happiness for some reason that is natural.

E.x. Just because I say that I have a natural right to be given a million dollars from the government, doesnt make it so.
