The actual cause of the issue between Jordan Baker and Nick is simple to understand. That’s why: Nick is disappointed in Jordan’s emotional reaction. For Jordan, it only matters how Nick treated her. And this is despite Myrtle’s recent death. He realizes she and the people of her social circle are egoistic and quite ruthless.
Detailed answer:
Scott Fitzgerald considers The Great Gatsby to be his best work. He raises the critical themes of his society at the time in the novel. The national idea of the American Dream is one of them. The author explores this idea thoroughly. F. Scott Fitzgerald concludes that the American Dream is a false concept. Its perception throughout the story is quite pessimistic. But it seems like there are some explicit examples of this statement. Successful people like Jordan, Tom, and Daisy care only about themselves. Gatsby died in pursuit of his personal American Dream. And Nick was disillusioned with this idea.
Scott Fitzgerald also explores the conflict between the old and the new aristocracy. Gatsby represents the materialistic, almost marginal wealthy people of West Egg. Jordan and others are reflections of the reserved and full of hypocrisy old nobility of East Egg. Meanwhile, Nick is an observer and commentator of this clash. Therefore, it can be said that the author sympathizes with the new money. He also criticizes the morals of the old nobility. The most remarkable aspect of it is a problem between Nick and Jordan. Nick’s thoughts express the author’s attitude towards such people as her. He says that Jordan makes him “rigid.”
