Nick compares the green bulk of America rising from the ocean to the green light at the end of Daisy’s dock. Just as Americans have given America meaning through their dreams for their own lives, Gatsby instills Daisy with a kind of idealized perfection that she neither deserves nor possesses. Gatsby’s dream is ruined by the unworthiness of its object, just as the American dream in the 1920s is ruined by the unworthiness of its object—money and pleasure. Like 1920s Americans in general, fruitlessly seeking a bygone era in which their dreams had value, Gatsby longs to re-create a vanished past—his time in Louisville with Daisy—but is incapable of doing so. When his dream crumbles, all that is left for Gatsby to do is die; all Nick can do is move back to Minnesota, where American values have not decayed.
