By including real life people in his play, Williams creates a sense of realism in A Streetcar Named Desire. Huey Long, Jr was the mayor of New Orleans from 1928 to 1932. Nicknamed the Kingfish because he thought of himself as a small fish when in DC, but a kingfish for the people in New Orleans. He was charasmatic and loved by his supporters, but charged by his opponents as being a dictator for his swift action. He was assisinated by a political rival's son in law in 1935 at the age of 42.
In Streetcar, Stanley refers to Long by alluding to one of his campaign slogans, "Every man a king." When he tells Blanche and Stella
Who do you two think you are? A pair of Queens? Now just remember what Huey Long said- that 'Every man's a king- and I'm the king around here.
Since Long's policies suggested in changes in financial polices to help those affected by the depression with his "Share the Wealth" program. Stanley is a supporter of these policies and the idea that every man can and should be the king of their own home.
