John Steinbeck's upbringing and socio-economic status deeply influenced his works, particularly his themes of class struggle and the human condition. Growing up in California, Steinbeck witnessed the challenges faced by migrant workers during the Great Depression, which became central to his narratives. His family's moderate economic background facilitated his understanding of both wealth and poverty, allowing him to convey authentic and empathetic portrayals of various societal classes. Steinbeck’s most famous works, such as The Grapes of Wrath and Of Mice and Men, reflect his dedication to social justice and highlight the resilience of the human spirit amidst hardship.
