The Primary Theme of "The Great Gatsby"

          I think that the primary theme of "The Great Gatsby" by F. Scott Fitzgerald is that The American Dream is an unsustainable ideal that gives people false hope and artificial happiness. I think that this theme fits all the criteria for the primary theme of  a novel. I think that it is the main message, saying that the American Dream was a corrupt ideal that would never bring real happiness, which was also a broad idea about life in the 1920s. Nick Carraway says several things throughout the book about how it is unsustainable, and keeps getting farther away, but he never really states that it is corrupt or impossible. One quote that is very important, and fits this theme very well without outright stating it is on page 134. It says "so he gave up, and only that dead dream fought on as the afternoon slipped away, trying to touch what was no longer tangible, struggling unhappily, undespairingly,  towards that lost voice across the room." This is also a point in the book where a major change seems to go through Gatsby, the protagonist. He seems to realize that the dream is corrupt, and he will never get to keep Daisy's wholehearted love.
