In "The Big Money," John Dos Passos explores the stark divide between different social classes in America during the early 20th century. He illustrates how wealth and power are concentrated in the hands of a few, while the majority struggle in poverty. This disparity is emblematic of the broader societal issues, reflecting the notion that the country could almost be seen as two distinct nations: one affluent and powerful, the other marginalized and struggling to survive.

The narrative captures the ambitions and disillusionments of various characters, showcasing how the pursuit of the American Dream often leads to betrayal and despair. Dos Passos effectively critiques capitalism, highlighting how it fails to serve the needs of the working class. This duality between the haves and the have-nots underscores a fundamental tension within the American identity, echoing the sentiment that we are, indeed, two nations.
