The African­American experience of growing up in America changed dramatically throughout the course of the twentieth century, thus leading to differing views between the older and younger generations. In Lorraine Hansberry's play,
A Raisin in the Sun
, the character Mama was raised during a point in time when racial prejudice was prevalent and blacks had virtually no opportunity to live out their dreams. On the other hand, her children,
Walter and Beneatha, and her daughter­in­law, Ruth, grow up in a world where slavery exists only in history books, and although they still face financial hardship and racial discrimination, it is possible for African­Americans to become successful business men or even doctors. The younger generation's concept of the American dream reflects the changing times and the new opportunities that are now available for African­Americans, showing the theme of generational differences.

Walter fantasizes about the way in which money would increase his social standing and allow him to acquire the material markers of class. Without room for advancement in his low­paying job as a chauffeur,
Walter is continually frustrated by his inability to fulfill the masculine role of financial
