America is a popular image in literature and film. Dozens of writers have tried to expose America's vices and evaluate the coherence of its values, morality and ethical standards. The pursuit of material wealth and the American Dream were the most frequently discussed topics in American literature in the 1920s. The effects of the First World War on individual beliefs and ideals, the continuing decay of morality, the emptiness of dreams and beliefs, and the inability to materialize one's life goals together created a complicated situation, which often resembled a journey for nothing.F. Scott Fitzgerald's The Great Gatsby and Ernest Hemingway's The Sun Will Rise are equally similar and different. The two stories are similar in their commitment to the failure of the American dream and its moral vacuity. However, the literary means and methods that the two authors choose to demonstrate their thesis are markedly different.

As an American modernist, Hemingway uses his simple and dialogue-oriented writing to attract readers, and Fitzgerald portrays Gatsby ambiguously through a narrator, Nick, to cynically describe American virtue and corruption, which substantially contributes to modernism in literature..
