How is Nick Different from the others?

Nick carraway is made the narrator he is a reliable one he tells us that he reserves all his judgments therefore the reader is lead to believe what he is saying is coming from an 3rd person objective point of view. Nick's history seems to be upper middle class and quite "normal" as opposed to the vapid elite of East Egg. Nick is a pretty credible character. He doesn't have any eccentricities and seems grounded. He was educated at the Ivy School Yale and fought in WW1. Nick isn't a character who needs anything. He seems to have enough money to settle down in West Egg. Nick observes situations without giving judgment. This allows the reader to trust Nick as a narrator and finally a character in the novel. Nick stands separate from the grandiose surreal world of East Egg.
