Which literary figure is known for satirizing the values of the upper middle class in his work?

The correct answer is F. Scott Fitzgerald. Fitzgerald is renowned for his keen observation and critique of the upper middle class, particularly in the context of the Jazz Age and the American Dream. His novel "The Great Gatsby" is a prime example where he satirizes the extravagances and moral decay of the wealthy elite during the 1920s. Through characters like Jay Gatsby and Tom Buchanan, Fitzgerald exposes the contradictions and superficiality of their lives, illustrating how wealth does not equate to true happiness or fulfillment.

While Jonathan Swift is known for his satirical works like "Gulliver's Travels," his focus was broader, often critiquing human nature, politics, and society as a whole, rather than specifically targeting the upper middle class. William Shakespeare's works encompassed a range of themes, including love, power, and ambition, but he did not primarily focus on social satire aimed at the upper middle class. Edgar Allan Poe is best known for his macabre tales and poetry, which delve into psychological themes rather than societal satire.
