Answer: He has come to associate the east with the ugliness of human nature and moral corruption.
Step-by-step explanation:
This question is referring to a novel by Fitzgerald ''The Great Gatsby'' and Nick Carraway is the narrator that moves trough all places in the novel.
- He is comparing both East and Midwest in the novel as the opposite ones because the East is considering a lack of human values, moral emptiness and it looked all grotesque to him.
- He didn't like the fast life as in the East so he decided to return to the Midwest.
