Why does the prospect of a job at the Dalton's make bigger mad?

The prospect of a job at the Daltons makes Bigger mad because it symbolizes a chance for upward mobility and acceptance into a world he feels alienated from due to systemic racism. He perceives it as a betrayal of his identity and values, as it forces him to conform to societal expectations that he resents. Additionally, the pressure to succeed in a job that represents white privilege exacerbates his feelings of frustration and entrapment, leading to a sense of anger and hopelessness about his circumstances.
