Answer:
Gatsby likely bought his home in West Egg because he can be closer to Daisy Buchanan.
Step-by-step explanation:
F. Scott Fitzgerald's "The Great Gatsby" revolves around the story of Jay Gatsby and his desire to be reunited with his former girl friend Daisy Buchanan, even though she had already been married to another man. The book also revolves around themes of social class, wealth, lost American dream, love, marriage, etc.
Though narrated by Nick Carraway, the neighbor of Gatsby and Daisy's cousin, the story's main protagonist is Jay Gatsby. While Daisy resides in East Egg, the wealthier part of the city, Nick and Jay's houses are situated on West Egg, the 'less fashionable part of the city. And Jay Gatsby's most likely reason for purchasing his home in West Egg seems to be that it will enable him to be closer to Daisy. This particular location is right across the bay from the Buchanan’s house.
