Fitzgerald's Depiction of the Time Period

I think that Fitzgerald's depiction of the time period is not really consistent. He goes back in forth talking about the wealth of some people and then the less fortunate people. On page 5 he says, "I lived at West Egg, the- well less fashionable of the two." Then he says, "Across the courtesy bay the while palaces of fashionable East Egg glittered along the water..." In one part of the state, there are fashionable, rich people and another part there are the people who aren't as fashionable and wealthy. This makes his depiction of the time period inconsistent.
