The character of Gatsby resembles F. Scott Fitzgerald more than Nick does. Fitzgerald was a romantic. He admired the rich. He came from a humble background, but he went to Princeton, a rich playboys school in those days, and picked up the habits and values of the rich. Then when he became a successful writer he had to prostitute his talents in order to keep making money to keep up with his wealthy friends. He married Zelda, who came from a prominent family and had expensive tastes. All his life Fitzgerald wanted to be rich and upper-class.He seems to be speaking about himself through Gatsby. His books were always about the rich, especiallyThe Beautiful and Damned, The Great Gatsby,andTenderis the Night. His short stories were also about rich, leisure-class people. He was a successful writer because the American public also admired and were curious about the rich. Then tastes and interests changed with the coming of the Great Depression, and Fitzgerald found that his subject matter was no longer in demand.
