She was appalled by West Egg, this unprecedented "place" that Broadway had begotten upon a Long Island fishing village
This line describes Daisy’s prejudices against new wealth and that culture, especially Broadway and the culture of rich people that come from there. The 1920’s was when Broadway first started to become a popular form of entertainment, as a result of the popularity and influence of Vaudeville. Broadway created a culture of celebrity obsession because Broadway shows in the 20’s emphasized the celebrities in them rather than the content, just like Vaudeville acts like Ziegfeld’s Follies.
In many ways, West Egg is a knock off of East Egg in the same fashion that plays on Broadway have sets in place of reality. West Egg, this “Long Island Fishing Village,” is a pretender to the nobility and wealth contained on its twin island. Thus, the people living in it are actors and posers, and in Daisy’s opinion, not as good as the real deal. In this context, West Egg has become the place for newly wealthy people who got their money from Broadway success to live their lavish lifestyles, and Daisy resents them because these newly wealthy people created this “unprecedented” place instead of actually being born in and a part of the upper class. She sees it as no more than some pompous houses on a “Long Island Fishing Village.” She didn’t care if they were famous because all that matters to her is whether or not someone was born into wealth.
The following passage includes Nick’s personal analysis of Daisy. Although it seems accurate, it’s important to keep in mind that the novel isn’t being narrated by Fitzgerald or some completely omniscient narrator. This is Nick’s understanding of Daisy.
