Core Themes & Central Ideas
Chapters 21-25 expand on two defining themes: the dehumanization of migrant workers by corporate and landowning systems, and the power of collective solidarity. Steinbeck contrasts the greed of those hoarding resources with the quiet resilience of groups sharing food, shelter, and hope. These chapters also emphasize the gap between legal justice and moral justice, as vulnerable families face exploitation with little recourse. Focus on how these themes tie back to the novel’s overarching critique of 1930s American capitalism.
