A Raisin In The Sun
Walter - He is the main character of the play and the father.  He is a cab driver who has the dream of being a bartender who is rich and successful.  He takes most of the $10,000 to invest it in a bar.  He realizes that he was scammed and he lost all of the money (which angered Mama).  He was offered thousands of dollars to move out of the neighborhood (because African Americans living in a white neighborhood lowered the value of the houses).  Throughout the play, he considers the offer, but at the end he says no.  Walter, at the end of the play, may have lost a lot of money, but he keeps his dignity and learns a big lesson.
