What are some examples of metaphores in the grapes of wrath?

In "The Grapes of Wrath," John Steinbeck uses metaphors to convey deeper meanings about hardship and resilience. For example, the journey of the Joad family to California is often compared to a pilgrimage, symbolizing hope and the search for a better life. The dust storms that ravage their homeland serve as a metaphor for despair and destruction, representing the broader economic and environmental crises of the era. Additionally, the character of Tom Joad embodies the metaphor of the "everyman," illustrating the struggle of the common worker against systemic injustice.
