The Great Gatsby is a criticism of the obsession with wealth and success. In the story, Gatsby and Daisy seem to have the "ideal" life of the 1920s. They are both young, attractive, successful and wealthy. They are also popular people who host lavish parties and have "fun" all the time. However, this decadence is in fact a way to hide their dissatisfaction. Their fates are tragic, and the reality is that they are utterly alone. Moreover, Fitzgerald is trying to criticize the idea of the American dream, which places an undeserved importance on wealth and success.
