Yes, the novel is about concrete living relationships, a man's love for a woman, a woman's betrayal of that love. But it is also about wealth, its great attraction as well as its destructive power, the carelessness that comes with it, and, yes, it is about the American dream, a dream of power and wealth, the beguiling light of Daisy's house and the port of entry to America. It is also about loss, about the perishability of dreams once they are transformed into hard reality. It is the longing, its immateriality, that makes the dream pure.
