Who said that Beneatha should just marry George?

Although Lena and Ruth admire George Murchison's financial success, they do not overtly tell Beneatha that she should marry him. When they question Beneatha about George, Beneatha responds by telling them that he is an arrogant snob. Beneatha goes on to insist that she is not concerned about her financial security because she is going to become a doctor one day. In the final act of the play, Walter Lee experiences a dramatic transformation by refusing to sell Lena's home back to the white community, and the movers arrive to take the Younger family's belongings to their new home in Clybourne Park. When Beneatha informs her mother that Joseph Asagai asked her to marry him and move to Africa, Walter Lee responds by saying, "Girl, if you don’t get all them silly ideas out your head! You better marry yourself a man with some loot..." (Hansberry, 149). Beneatha then asks her brother what he has to do with who she marries, and Walter Lee says, "Plenty. Now I think George Murchison—" (Hansberry, 149). After Walter Lee suggests that Beneatha should marry George Murchinson, the siblings begin to argue and leave the apartment yelling at each other.
