Where does the ego come from?

In all of the places that I have been, I have not experienced self-centredness and egocentrism quite to the extreme that infects the American (as in the United States of America) conscience anywhere else. So I got to thinking… where does it come from? What about America (as in the United States of America) is it that breeds this mentality? Are Americans (as in the United States of America) raised to believe that they are better than people inhabiting the rest of the world? I guess it is true, if 110 persons incarcerated per 100,000 people is a cause for bragging. Don’t get me wrong, I am not saying that Americans aren’t awesome people, or that, for the most part, they aren’t worthy of esteem. In fact, this wasn’t supposed to be about Americans at all. I am merely questioning the origins of this narcissistic mentality. I don’t remember my mother ever telling me “Now honey, you are better than everybody else. Don’t ever forget that.”. Perhaps my upbringing was merely lacking in ego coaching.Freud declares that “The Ego and the Id are built upon the presupposed existence of conscious and unconscious thoughts.”.  The question that remains, is, aren’t we taught how to think by our parents? Where exactly do these thoughts come from? Isn’t our unconscious thought predicated upon our learning and experiences? What are your thoughts, and even more importantly, do you believe that religion has played a role in the formation of the self importance that you see exemplified by others, or does a pre-existing feeling of superiority merely spill over into their religious life?
