The Great Gatsby - Battle of the Eggs

"I lived in the West Egg, the - well, the less fashionable of the two, though this is a most superficial tag to express the bizarre and not a little sinister contrast between them." p. 9

First of all, I was a little confused as to why they refer to the sections of lands or islands as "eggs". It just seems a bit odd. That aside, I think the difference between the East and West Eggs are hard to miss. The most obvious difference is the contrast between wealth. Those on West Egg are described as "new money"; that is, they just came into money and have not yet made it into the close-knit society of the aristocrats. Those on East Egg have a lot of money and belong to the social group that share that commonality. In short, the East Egg-ers are seen as more sophisticated. However, I believe that that is merely on the surface. They are, as far as I can tell, people who like to lie, party, and get drunk. That does not seem very sophisticated to me. Nick, who lives on West Egg, appears more sophisticated because he does not lie, attends a few parties, and has only been drunk twice, thus making him more sophisticated.
