Gatsby is, of course, both the novel's title character and its protagonist. Gatsby is a mysterious, fantastically wealthy young man. Every Saturday, his garish Gothic mansion in West Egg serves as the site of extravagant parties. Later in the novel, we learn that his real name is James Gatz; he was born in North Dakota to an impoverished farming family. While serving in the Army in World War I, Gatsby met Daisy Fay (now Daisy Buchanan) and fell passionately in love with her. He worked briefly for a millionaire, and became acquainted with the people and customs of high society. This, coupled with his love of Daisy, inspired Gatsby to devote his life to the acquisition of wealth.
After the birth of their child, the Fitzgeralds moved to Great Neck, New York , on Long Island , in October 1922. The town was used as the scene of The Great Gatsby .  Fitzgerald's neighbors in Great Neck included such prominent and newly wealthy New Yorkers as writer Ring Lardner , actor Lew Fields , and comedian Ed Wynn .  These figures were all considered to be " new money ", unlike those who came from Manhasset Neck or Cow Neck Peninsula , places which were home to many of New York's wealthiest established families, and which sat across the bay from Great Neck. This real-life juxtaposition gave Fitzgerald his idea for "West Egg" and "East Egg". In this novel, Great Neck (King's Point) became the "new money" peninsula of West Egg and Port Washington (Sands Point) the old-money East Egg.  Several mansions in the area served as inspiration for Gatsby's home, such as Oheka Castle  and Beacon Towers , since demolished. 
After the 1920s, many presidents supported the idea of the Dream as a pursuit of material benefits. President Roosevelt outlined an Economic Bill of Rights in his 1944 State of the Union address. He defined the pursuit of happiness as decent housing, a good job, education and health care. FDR realized that people who were hungry, homeless and sick were more likely to succumb to strong social forces. He worried about fascism , Communism and Socialism movements that were sweeping the world at that time. For more, see FDR's Unfinished Second Bill of Rights .
