When and why did "Selfishness" become "Patriotism"?

I really don't know what you are asking. However, I would like to tell you about a book I read in college. It was The Virtue of Selfishness" by Ayn Rand. It opened my eyes to a concept that I didn't quite realize before I read it. Basically, it states that selfishness is a very powerful human emotion, far more powerful than altruism. While most religions paint selfishness as an evil, the truth is that selfishness can indeed be a virtue, if properly channeled into constructive pursuits. This explains why the most prosperous societies on Earth are Capitalistic, while Socialistic/Communistic societies always fail by being drowned in poverty. "The people pretend to work and the government pretends to pay us" is the wisdom of the Socialistic system. So I guess it is true that if you believe in your country and want it to be rich, powerful, and prosperous, then you want it to be Capitalistic, or "Selfish" if you want to label it that. The Korean peninsula is the best example of this, where the young boys of the socialistic north are a full 6 inches shorter in height than the boys of the south, despite the fact that they have the same identical gene pool; Where people of the north have to catch robins and sparrows in order to get some protein in their diet, because they have already eaten all of the rats and mice. Which Korea would you like to live under? The "selfish" south or the one with the world's greatest golfer, Mr. Kim Jong Il?
