I lived at 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.
Nick is from West Egg which represents new wealth. It is described as “the less fashionable of the two” implying that old wealth or being born rich is thought of as better. This is backwards from todays society where working and earning your money is more respectable than inheritance.
He goes on to use the word “sinister” when comparing East Egg to West Egg. It is a extreme word to use giving the thought that the people from East Egg received their money through corrupt or dishonest means.
There is also wordplay here —– West Egg is located to the left of East Egg; “sinister” comes from the Latin for “left.”
