Read Franz Oppenheimer, The State.
"The State, completely in its genesis, essentially and almost completely during the first stages of its existence, is a social institution, forced by a victorious group of men on a defeated group, with the sole purpose of regulating the dominion of the victorious group over the vanquished, and securing itself against revolt from within and attacks from abroad. Teleologically, this dominion had no other purpose than the economic exploitation of the vanquished by the victors."
"No primitive state known to history originated in any other manner. [1] Wherever a reliable tradition reports otherwise, either it concerns the amalgamation of two fully developed primitive states into one body of more complete organisation, or else it is an adaptation to men of the fable of the sheep which made a bear their king in order to be protected against the wolf. But even in this latter case, the form and content of the State became precisely the same as in those states where nothing intervened, and which became immediately 'wolf states'." (p. 15)
If you never understand anything else about politics, understand this. Every government on earth, without exception, traces its origins back to some bandit who one day rode into a peace-loving village and said, "now you are working for me!"
Government exists for the sole purpose of subjugating and exploiting a supine populace. Those primitive bandits have gone to finishing school since then. They no longer ride about with unkempt hair and leggings covered in the blood of their victims. Nowadays they have nice manicures and three-piece suits and smile for the cameras, but their heart and soul hasn't changed. They build new hospitals and open art galleries and expect us to be grateful, but their evil is no less. If I give you a nice shot of morphine to keep you quiet while I anally rape you, you might have a pleasant time, but it doesn't make me a good person. That's the advance of modern times over neolithic barbarianism -- now the swine in power give us lovely little morphine injections before slamming it into us.
When you make excuses for some gangster, saying "sure he sent my neighbour's kid to die in some third world country, but I'll vote for him anyways because he's increasing funding for local hospitals" you are basically saying, "I forgive him for raping us because he gave us this really cool morphine!"
