Nick knows how shallow and selfish Tom and Daisy are. He despises them precisely because they despise Gatsby. See the explanation below:

Explanation:

This question refers to "The Great Gatsby," a novel by American author F. Scott Fitzgerald (1896-1940) in which themes such as the decadence of the American dream and the corruption of society are developed.

Nick is the narrator in the novel. He and Gatsby, the main character, are neighbors. Gatsby is in love with Daisy, who happens to be Nick's cousin. Daisy is married to Tom Buchanan.

As the plot progresses, we get to see how despicable Tom and Daisy are, at least to Nick's eyes. They are selfish people who place their desires ahead of anyone else's.Tom in unfaithful to Daisy. He is a sexist and racist man who is only rich because he inherited his money. Daisy also comes from a well-off family. She betrays Tom with Gatsby, and her life is dedicated to avoiding boredom.

Gatsby, on the other hand, was born extremely poor. He is a millionaire now, but only because he went into shady business, such as selling alcohol illegally. When he tries to break Tom and Daisy up, Gatsby is humiliated. Tom and Daisy look down on him, considering themselves his superior. They are old money, Gatsby is new money. They have faults and sins, but Gatsby's seem worse in their eyes. That is why Nick says they are a "rotten crowd". Who are they to judge Gatsby? Why would they think they are better than him when his heart is pure while their hearts are vile? Gatsby became a criminal and made money just because he wanted to be with Daisy. To Nick, that dream is incorruptible, and Gatsby deserves admiration.
