The separation between the east and the west shows the division between the people who are from each side. Generally, the West Coast represents a more laissez-faire attitude and is seen as the "new" land or world. Many people have dreamt of "going west" in search of a new life or vast treasures in the "wild" lands. Fitzgerald associates these qualities of the West with the characters Nick Carraway and Jay Gatsby, who live on the West Egg. On the other side of the spectrum lie Tom Buchanan, Daisy, and Jordan Baker. These characters are associated with a stereotypical East Coast mindset which is more strict, traditional and ancestrally based, as opposed to the "new" and "wild" West. They resent anything that is unfamiliar to them such as the West Eggers with "new money" and no traditions. The distance and mindset of the East and West are symbolically integrated into the East Egg and West Egg which are representative of the social class of which the characters come from.
The physical settings establish the identities of the characters through their wealth and houses. The West Eggers represent the social class of the nouveau riche, people who have made fortunes recently in their generation
