In Sinclair Lewis's "Main Street," the author emphasizes the idea that those who aspire to help the common people often underestimate their capabilities. He suggests that many well-meaning individuals who seek to take action on behalf of others may be misguided, as the very people they intend to assist possess the potential to help themselves. This notion challenges the assumption that external intervention is necessary for the common good.

Lewis's assertion highlights the importance of recognizing the strength and agency of individuals within a community. The statement suggests that once the common people become aware of their own power and abilities, they will take initiative to improve their lives and circumstances. This perspective encourages self-reliance and empowerment, suggesting that real change comes from within the community rather than from outside influences.
