The story is narrated by Nick Carraway, a restrained calm youngster, who never stepped into the circle of the upper class. Before moving to West Egg, he never had the idea of who Gatsby was; and at the very start, he always heard some rumors about him. However, he should gradually build a respect for him, which came from some kind of fulfillment-because Gatsby did what he dreamt of doing-it was like Gatsby was another personality of him. He was brave and capable enough to do anything in his desire. So even if what Gatsby told him sounded totally absurd, he managed to believe it. He knew he loved Jordan Baker-but he only kept this in his mind.
Jordan Baker was an anticipated modern woman. She seemed to get closer to Nick as time went by; but at last she told him that she'd been engaged. A lie or not, it didn't matter much. She was utilitarian enough.
Tom Buchanan, a masculine version of Jordan Baker, was an arrogant man with much complacency. He acted like he ruled the world-he even cheated on Daisy so blatantly. His mistress did have something appealing, but creeping could never be moral. He despised Gatsby's Oggsford identity, saying he was nobody from nowhere, well, he was right,because the grotesque society thought so.
The society couldn't accept an upstart like Gatsby. As a matter of fact, when Daisy first met him, she considered him an aspired officer, so she "fell for him". Gatsby knew it. Knew it from the start. So he said "her voice was full of money", seeing through the cruel truth, but he still fielded for this irrealizable romance.
As I suppose, Daisy is much more sophisticated than she noticed herself. She said she wanted her daughter to be as foolish as she did, but she knew it all about the social, financial and reputational issues. She knew she never loved Tom and he was cheating on her, but she was clever to endure and keep her glamorous life. When realizing that Gatsby was still nobody,she gave up on him and chose to stay with her unfaithful husband.She was the focus of all people, and she utilized this advantage to make herself happy.
But what is happiness? Gatsby is a smart guy, what he did was never pointless. From childhood, he struggled to learn about eloquence and other practical skills; he tried so hard, I've never seen a man so determined, even in the literary works, never before. The persistence is based on his long-time dream of an unreal love affair, like a green light keeping gleaming.
What Fitzgerald wanted to illustrate is the disillusion of a typical American dream. Gatsby was an upstart, so fresh and vigorous, but he still wore a pink suit, which was gaudy and a bit ridiculous (but he never perceived it), and his incessant pet phrase"old sport" to prove he'd stayed in Oxford never sounded decent. Nevertheless, he faked hard to be like Tom, like Daisy, like the people he wanted to be and be with, but he couldn't make it. It's in his descent,inseparable from his acquired transitory success.
It's all about predestination. Gatsby quested his green light, and to some extent he was a hero, with nothing left but his father's meaningless pride. When the party was over, when the spree ended, when nobody came to his funeral, only Nick, the sober penniless man, understood him. It's the world of money, it's the world of cruelty. But it's also the world of dream, you dream, and you win. Let's forget about the result: Gatsby did right, so did Daisy, Tom and Jordan. They were the ones in the roaring twenties, the epoch of dreams. Although in a pink suit, Gatsby is still so admirable, his greatness lies in his desperate hope, a green light glistening through a fated tragedy.
