Bill Gates.

Bill Gates encompasses some of the key idea put forward in Crèvecœur's Letter from an American Farmer. There is a strong sense in the book that America was a place where, if you are industrious, you could flourish and reap rewards based on how hard you work. Bill Gates' has obviously achieved this. He is a Havard University drop-out and was arrested for a traffic violation in 1977. Despite these, with ingeunuity and inventiveness, he has become the 10th most powerful man in the world (According to the Forbes list has of 2011 - http://www.forbes.com/wealth/powerful-people#p_1_s_arank) and is the second richest man on the Planet.
It is said by Crèvecœur in the novel: "How thankful ought we to be, that they reared us in a Land, where sobriety and industry never fail to meet with the most ample rewards!" This is still alive today and many people in America still hold this value. Take, for example, Facebook founder and CEO, Mark Zuckerberg, along with the aforementioned buisnessman, Bill gates.
