what does the setting suggest about the characters in scene one?

At rise, we see a two-story building in a poor, charming, diverse section of New Orleans, called Elysian Fields. "They told me to take a street-car named Desire." Blanche's first action in the play is one of confusion, ambivalence, disorientation. She cannot believe where she has ended up, standing at her sister's rundown New Orleans door step, or determine how she got there, on a pair of streetcars named Desire and Cemeteries. The rundown working-class setting represents the lower end the social and economic scales. Everything about the setting screams "dead end" which is how the characters feel.
