In what way is The Great Gatsby an autobiographical novel? Does the character of Nick or the character of Gatsby seem most like Fitzgerald?

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.
