Analyze the theme of disillusionment in fitzgerald’s "winter dreams."

Dexter does work hard and becomes wealthy, but once he makes it to the top, he realizes that the dream has become corrupted (just like Daisy is the corrupted version of Gatsby's dream and can never live up to his expectations).

Both of these works present Fitzgerald's frustration with his own life and attempts to achieve the American Dream.  He, like Dexter and Gatsby, became interested in a wealthy socialite (Zelda) and was looked down upon by her social class and family.  When he finally did win Zelda and marry her, he endured a tumultuous relationship with her where their wealth was unstable and their faithfulness to one another questionable.  He believed (as he demonstrates in "Winter Dream") that the Old Money portion of society corrupts the moral, decent Midwesterner.

taking into account that a theme is the central topic a text treats and can be developed through a story, play, poem etc. the following are themes that can be further developed:  

my best friend jeffrey has many unusual interests. (the story could be about each of the unususal interests)

once a man gives his soul over to evil, he can never go back. (this could be a saying or a proverb)

the three sheepdogs lay around the yard all day. (it could be developed detailing how each of these sheepdogs lay around)

a priest's collar has an unusual effect upon people. (it could be developed detailing the different effect upon people)

innocence is a powerful force in a world full of corruption. (it could be developed detailing how is a world full of corruption)

king lear is a play shakespeare wrote later. (it is just a sentence and doesnt give any idea or topic to be discussed in details.

evil often wears the disguise of innocence. (this could be a saying or a proverb)
