Which is a stronger impulse in America: competition or fairness?

I have to write a research paper for my History cl and I need some help. I'm writing it on the question: 'Which is a stronger impulse in America: competition or fairness?'. I need proof. Please be as bias as you want, just I need you to back your self up with events from U.S. History. You don't have to explain if you don't want to, I'll look into the events. Thank You.
