The novel's narrator, Nick is a young man from Minnesota who, after being educated at Yale and fighting in World War I (like Gatsby), goes to New York City to learn the bond business.

This is shown to be falling apart through Gatsby. He works hard to achieve success, but the corruption of the criminal industry haunts his every action and he ultimately fails to acquire what he really wanted: Daisy
Old vs New money
