Weaving together economic theory, psychology, and the histories of immigration, industrialization, class formation and slavery, Roediger in this work addressed what has become a common question in labor history, specifically, and American political culture more generally: why, historically, have working class blacks and whites not found common cause in their shared suffering at the bottom of the social ladder? (W. E. B. Du Bois also posed this question in his seminal work, "Black Reconstruction" (1935), as he saw a failure of labor in creating connections across racial lines.) In the 19th-century context where the small-scale, autonomous craftsmen were being replaced, slowly but inexorably, by the factory system – with great consequences for the "liberty" of ordinary Americans, Roediger suggested that for workers to embrace "whiteness" and a caricatured representation of black slaves provided them with a meaningful symbolic "wage," replacing the status values of independence and craft skill for workers.
