Gatsby as the Young Fitzgerald; Nick as the older Fitzgerald?

The narrator of The Great Gatsby is Nick Carraway who closely resembles the his creator, F. Scott Fitzgerald:

• Nick Carraway comes from a "prominent, well-to-do people in this Middle Western city for three generations." Fitzgerald comes from Minnesota, a middle western city where his mother's family, the Keys have resided for three generations.
• Nick Carraway has a well known "great-uncle" he is "supposed to look like. Fitzgerald was related to composer Francis Scott Key.
• Nick Carraway describes himself as being "rather literary" at Yale just as Fitzgerald contributed to publications and theatre productions at Princeton.
  
• Nick is fascinated by the wealthy elite and becomes a temporary participant in their social circles, but remains critical of their disingenuousness and hedonistic lifestyles. Fitzgerald and his wife Zelda's lives mirrored those of the party scenes in Chapter 3, criticized his generation as a race "going hedonistic."
  
• Fitzgerald wrote, "Show me a hero and I will show you a tragedy." Nick's sentimental take on Gatsby is our first introduction to Gatsby, "who represented everything for which I have an unaffected scorn. If personality is an unbroken series of successful gestures, then there was something gorgeous about him, some heightened sensitivity to the promises of life"
