Audience members may well see Stanley as an egalitarian hero at the play’s start. He is loyal to his friends and passionate to his wife. Stanley possesses an animalistic physical vigor that is evident in his love of work, of fighting, and of sex. His family is from Poland, and several times he expresses his outrage at being called “Polack” and other derogatory names. When Blanche calls him a “Polack,” he makes her look old-fashioned and ignorant by asserting that he was born in America, is an American, and can only be called “Polish.” Stanley represents the new, heterogeneous America to which Blanche doesn’t belong, because she is a relic from a defunct social hierarchy. He sees himself as a social leveler, as he tells Stella in Scene Eight.

Stanley’s intense hatred of Blanche is motivated in part by the aristocratic past Blanche represents. He also (rightly) sees her as untrustworthy and does not appreciate the way she attempts to fool him and his friends into thinking she is better than they are. Stanley’s animosity toward Blanche manifests itself in all of his actions toward her—his investigations of her past, his birthday gift to her, his sabotage of her relationship with Mitch.

In the end, Stanley’s down-to-earth character proves harmfully crude and brutish. His chief amusements are gambling, bowling, sex, and drinking, and he lacks ideals and imagination. His disturbing, degenerate nature, first hinted at when he beats his wife, is fully evident after he rapes his sister-in-law. Stanley shows no remorse for his brutal actions. The play ends with an image of Stanley as the ideal family man, comforting his wife as she holds their newborn child. The wrongfulness of this representation, given what we have learned about him in the play, ironically calls into question society’s decision to ostracize Blanche.
