Why is Mr. Deeds Goes to Town considered a David-versus-Goliath story?

Mr. Deeds Goes to Town (1936) is characterized as a David-versus-Goliath story because it depicts a principled, common man battling against powerful, cynical forces of injustice.12

In the film, Longfellow Deeds—a modest, small-town writer—moves to New York City after inheriting a fortune. He is quickly targeted by manipulative figures, including his uncle’s conniving lawyer, who represent the selfish interests of big business. When Deeds attempts to use his wealth to help the poor and downtrodden during the Great Depression, these powerful antagonists question his sanity to seize control of his inheritance.12

The film serves as a populist fable where the "little person" must exert moral force to overcome the corruption of those in positions of power. Like many of director Frank Capra’s works, the narrative celebrates the triumph of an idealistic, courageous hero over shrewd and amoral power brokers, highlighting the strength of the individual against overwhelming societal pressure.2
