What's wrong with greed? The Protestant work ethic is nothing more than greed given divine rationalizations. This country is founded on greed.
You are a victim of your liberal revisionist education. America was corrupted but it was corrupted by secular humanists like you who are trying to rewrite our Constitution and erase God from the public domain (yet, iroinically - you supported a Chrsitian - McClintock!). You want to know why Europeans came here? Read the Mayflower Compact - it clearly says they came here for "ye glory of God and advancement of ye Christian faith" and also to escape the tyranny in Europe. You have read the Mayflower Compact haven't you - it's the first official government document in America.
