At the end of the story, what does Kazem say is the difference between having money at home and in America?

When he returned to Iran, Kazem was treated as a man of wealth and substance because of the way he'd helped the needy in his homeland. When he returned home, Firoozeh asked him how it felt to come back to America after visiting his homeland where he was treated like a rish man.... Kazem told his daughter that he was rich in America too.... the moeny just didn't go as far.
