In Great Gatsby, Fitzgerald showed us that one of the major topic explored in this novel is the sociology of wealth, especially how the newly minted millionaires of the 1920s differ from and relate to the old aristocracy of the country rich families, who had important names. In the novel, people who lived in West Egg represented the newly rich as Gatsby, while East Eggâ€™s people, especially Daisy and Tom, represent the old money people. He portrayed the newly rich as being vulgar, gaudy, ostentatious, and lacking in social graces and taste. Gatsby, for example, lived in a monstrously ornate mansion, wears a pink suit, drives a Rolls Royce, and does not pick up on subtle social signals, such as the insincerity of the Sloanes invitation to lunch. In contrast, the old money people possessed grace, taste, subtlety, and elegance, epitomized by the Buchanan tasteful home and the flowing white dresses of Daisy and Jordan Barker.
Also the other major theme is American dream, which symbol is Gatsbyâ€™s Dream. Gatsbyâ€™s dream of Daisy and the perfect life he believes he could have with her. When Nick first met Gatsby, he is shocked to discover the man, who he thought is really normal, is Jay Gatsby himself. Fitzgerald had every reason to make Gatsby seem normal; he is a living symbol of the Jazz Age American Dream, with its quest for money, success, and a life of leisure. The American Dream for most Americans had simply been to live and work without fear of repression. All of Gatsbyâ€™s energy is directed towards Daisy. She is beautiful and charming, but also fickle, shallow, and bored. Daisy is the most important part of Gatsbyâ€™s dream and for Gatsby; Daisy embodies everything that the American Dream is. Gatsby bought a house in West Egg, in the hopes that he would win Daisy back. Gatsbyâ€™s love for Daisy has less to do with Daisyâ€™s inner qualities than with Gatsbyâ€™s own.
