The freshest part of Jay Gatsby's dream is that throughout the narrative, he remains idealistic. At the end of the novel, Tom reflects,
Gatsby believed in the green light, the orgastic furture that year by year recedes before us....
Because of his genuiness and idealism, Tom tells Gatsby shortly before his death,
They're a rotten crowd....You're worth the whole damn bunch put together.
Gatsby has always looked for the green light at the end of Daisy's pier, but in reality he is the only light in the amoral world of decadence in which he strives.
