American's blame others for their selfish actions, thus denying responsibility for these actions. You can choose one of these if you like, but you must rebut the other.
People get the things they want and then they want more.
I think even I have had my times of being selfish. Like when I got a car for my sixteenth birthday I didn't let my friends drive it even thought they had their license. I made them get their own car. As people become more selfish and don't find ways to change then I think not to many positive things can come from it. The article is right about people wanting to get ahead in society.
