Why politics is ubiquitous? discuss?

I perhaps view politics a bit in reverse from most people. I see it as an expression of society and the state of a culture. Not only are politics ubiquitous but one can only understand them when they see them in every day life. 

It's like a river. If you want to study a how a river flows, you can't scoop some water up. You have to understand several factors to why a river flows. Trying to isolate it will never reveal even that simple thing to you. If you really want to understand politics, study psychology and sociology. Study military history and especially study mass movements. 

Only studying the specific occurrences is really just a matter of memorization, you won't ever understand politics until you realize that it being ubiquitous is a fundamental principle of politics. Don't get caught up on looking at one puzzle piece that you never realize where to put it.
