What examples does Steinbeck use to show that Americans are restless and dissatisfied?

In "The Grapes of Wrath," Steinbeck depicts the Joad family's constant movement and search for better opportunities as a reflection of Americans' restlessness and dissatisfaction during the Great Depression. The characters' continual struggles to find work and stability, as well as their feelings of alienation and disillusionment, serve as examples of this pervasive restlessness. Steinbeck highlights how economic hardship and social injustice fuel a cycle of discontentment and yearning for a better life among Americans.
