Final answer:
Fitzgerald portrays Gatsby's pursuit of social mobility and the American Dream as a cautionary tale, highlighting the dangers and ultimate tragedy accompanying such endeavors.
Step-by-step explanation:
Taking into consideration the various sources about Gatsby's personal life, F. Scott Fitzgerald seems to be illustrating that Gatsby's story serves as a cautionary tale about the American Dream. Although Gatsby's wealth and determination place him among the elite, his story underlines the disillusionment and ultimate tragedy encountered when chasing an idealized social status. His relentless pursuit of Daisy and assimilation into high society are underscored by his inability to truly become a part of the old-money class. In essence, Fitzgerald conveys the futility and inherent risks involved in attempting to change one's social standing through artificial means, such as accumulating wealth.
