What makes Amory Blaine uniquely American

For this literary analysis I have chosen the main character, Amory Blaine from F. Scott Fitzgerald’s This Side of Paradise. Here is the assignment instructions: For your project, you should choose a character from the novel you have read. Explain what makes that character uniquely American. Please feel free to think outside the box. There are characters within these novels that may not be legally or technically American but are tremendous examples of the American spirit. This gives you a lot of opportunity to really explore a character that interests you.
You will need to incorporate many aspects of the novel to prove your case. Be sure to look at issues such as imagery, dialect, social and cultural influences, and point of view, among others.
