Here's why:
* Social Satire: The story critiques the excesses of the wealthy, their materialism, and their detachment from the realities of the working class. Fitzgerald mocks the values of a society obsessed with wealth and status. The extravagant lifestyle of the fictional "Ritz family" and their disregard for everyone else serves as a sharp commentary on the societal problems of the Roaring Twenties.
* Fantasy Elements: The story incorporates elements of magic and the supernatural, specifically the existence of the "Ritz family" who are imbued with supernatural power and wealth. The diamond serves as a magical artifact, symbolizing the corrupting influence of wealth.
However, the satire dominates the story:
* Focus on Societal Commentary: Fitzgerald uses the fantasy elements as a vehicle for his social critique. He exaggerates the characteristics of the wealthy class to make a point about their moral failings and their impact on society.
* Humorous Tone: Despite the serious nature of the satire, Fitzgerald employs a humorous tone and exaggerated characters, making it a satirical piece rather than a pure fantasy story.
Ultimately, "The Diamond as Big as the Ritz" blends fantasy elements with social satire to create a powerful and thought-provoking story about the dark side of American wealth and the consequences of unchecked greed.
