Answer and explanation:
"The Great Gatsby" is a novel by American author F. Scott Fitzgerald in which the theme of hypocrisy is developed from cover to cover. Narrated from a first-person perspective by the character Nick, who functions more as an observer at the beginning, the story shows us how society has no shame in claiming to possess certain values while having none.
Underneath a layer of wealth, universities, fine dresses, and fancy hotels, the characters have no moral, no sense of justice, be it worldly or divine. They have affairs and, when they don't, they feel pleased to watch others having affairs. They lie, they hide their past history, they don't raise their own children, yet they are quick to point fingers and judge anyone.
Perhaps the best example is the character of Tom Buchanan, Gatsby's enemy, so to speak. Tom married Gatsby's love, Daisy, only to cheat on her and pay no attention to their daughter. He constantly leaves Daisy alone and has wild nights with his lover and her friends at a hotel in New York. Nonetheless, because he was born rich and attended some fancy school, Tom believes to be superior. He is hypocritical enough to judge Gatsby, to address him as if he is worth less than himself. Gatsby was born poor and made his wealth by selling alcoholic drinks, forbidden at that time. Tom chooses not to see his own sins, acting as if he is immaculate and accusing Gatsby of being immoral.
