Walter hopes to open a liquor store with Mama's money and have a supporting family who he can later give everything to, especially his son Travis.
Mama's Ambition
Beneatha's dream is to become a doctor and cure people. Marriage isn't at the top of her list but she would like to experience that one day.
Walter's Next Move
Ruth would like to get a new home some day but she knows they don't have that kind of money so she settles for what she has.
Lindner's rejection
Mamas dreams are similar to Ruth's and just wants the best for her family. With her insurance money, she put down a payment on a home.
With the money that was left, Bobo and him entrusted the money to Willy to invest into a liquor store. Willy later betrayed them and took off with the money.
With the Younger's being the only black family in a white community, Lindner offered them a deal in return of their leave, which Walter rejected.
