In the play A Raisin in the Sun by Lorraine Hansberry, the protagonist Walter wants the ten thousand dollars of insurance money from his father's death. He wants it so he can fulfill his dream of owning a liquor store. His mother does not give him the money. There are three reasons why she does not give him the money.

It is only at the end of the play do we finally see Walter begin to mature and show some responsibility for both his actions and his family. He refuses the offer from Mr. Linder to reconsider moving into their all-white neighborhood and plans to move in to their new home. Also he supports his family's dreams.
