Daisy and Gatsby were pre-war lovers that become separated by the war and the overbearing difference in social class, Gatsby was poor and believed he was unworthy of Daisy, determined to make something of himself Gatsby leaves. Daisy is madly in love with Gatsby, but marries Tom Buchanan, the richest man in east egg, straight after she gets a letter from Gatsby, asking her to wait until he becomes a rich man so they can be wed. Scott Fitzgerald uses this situation to portray a major ideology in the novel and of the time; that enough money can buy love. This is still relevant today as we constantly see Hollywood's rich and famous will marry not out of love, but out of the desire for publicity and money.
Gatsby, now a rich man who hosts extravagant parties every weekend but barely reveals his identity, is likely the most talked about person in New York, yet almost no one knows anything real about him. Throughout the novel our bank of information surrounding Gatsby grows, as we know nothing of him at the beginning, wild rumors spread around by the city folk New York are the only prior knowledge we have of Gatsby. "Well, they say he's a nephew or a cousin of the Keiser Wilhelm's, that's where all the money comes from" This quote from
