Final answer:
The Lost Generation artists and writers, notable figures like F. Scott Fitzgerald and Ernest Hemingway, rejected post-WWI American values and the American dream, choosing to live as expatriates in Europe and expressing their disillusionment through their works.
Step-by-step explanation:
The artists and writers of the “Lost Generation” rebelled against post-World War I ideals. This group of intellectuals became known for their feelings of disillusionment in the wake of the Great War, and often took satirical shots at the middle class and traditional American society through their works. Writers such as F. Scott Fitzgerald, Ernest Hemingway, Sinclair Lewis, Edith Wharton, and John Dos Passos expressed a sense of hopelessness and criticism toward contemporary American values, leading many to embrace expatriate life in European cities like Paris and Rome. These writers frequently engaged with new forms of literature and were closely connected with Modernist movements, rejecting the optimism of the American dream in favor of a more critical and introspective approach to writing.
