Pizzazz and Class

"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. [...] Across the courtesy bay the white palaces of fashionable East Egg glittered along the water, and the history of the summer really begins on the evening I drove over there to have dinner with the Tom Buchanans."

Nick is talking about the two "types" of civilizations... The hard-working West Egg and the ever so glamorous East Egg.

I lived with less pizzazz and class in West Egg, even though this is a snobby way to differentiate them. Across the water, I can see the sparkling buildings of the beautiful East Egg. The city and water dividing us seemed to glow as the sun hit it just right. The rest of the story unwinds as I visit the elegant city for dinner with the Buchanans.
