Well, hard-wired is a strong word. But you are just referencing human nature after all. Government is all about human nature. Anything that relies on the premise that people will be benign and serve others (which by the way is not the same thing as just being unselfish) is going to fail at some point. That is why the founding fathers created the system of "checks and balances", which has since been somewhat circumvented. It was a measure for controlling human selfishness and ignorance, a system meant to bring out the most security and freedom with the least government intervention into daily affairs. For that reason the citizens of the US enjoy the most freedom and success of any nation of the earth. Freedom is slowly decreasing, but the proof of the system is its long-term success. It will only be broken when the government finally, truly controls the people. It doesn't seem to be far off, sadly.
As much as we call it a "Democracy", it's still a republic in reality, it still maintains its core premises (though many have been trying to change them lately) and thus we still enjoy its success. Whether you like the US or not, it's the most advanced and successful government in the world (for now). Thank God that Obama doesn't have the power to do what he says! The Presidents really don't have a lot of power nowdays, which is why Bush was such a joke by the end. They're puppets and scapegoats. But the intent of the founding fathers was to balance the power between that of individuals and the masses. Less successful governments (insofar as their purpose is to provide for the people) are those which fail to create and maintain this sort of balance, examples being dictatorships and mob governments (pure democracies, communism, and socialism, which all usually end up just circling back into dictatorships or oligarchies as they fail).
By religious indoctrination, you mean actually educating people to believe something? It doesn't need to be religious in nature, though that is the only thing that sticks because we have a natural need for God. Not trying to drag us into a religious debate, just asking for clarification.
