Social criticism in American literature has been a powerful force for exposing societal issues and advocating for change. From the late 19th century to the present, authors have used their works to challenge injustices, inequality, and oppression, reflecting the cultural and political realities of their times. Key themes include racism, poverty, gender inequality, and the pursuit of the American Dream. Major works like "The Jungle," "Native Son," and "Beloved" have raised awareness, inspired activism, and influenced public policy, demonstrating literature's enduring impact on American society and its ongoing relevance in addressing contemporary challenges.
