The Crucible Chapters 1-5

In The Great Gatsby, F. Scott Fitzgerald criticizes the people in the 1920s via the symbolic elements that intertwine with his characters in his novel. 
The first symbol is the difference between East and West Egg. In West Egg, people have "new" money. While they are generally as wealthy as those in East Egg who have "old" money, there is a definite disparity between the two. Tom and Daisy are examples of characters who possessed "old" money, and Nick and Gatsby have more "new"money. This is significant because Gatsby is in love with Daisy, but they are from two different back grounds. Gatsby has spent the past five years of his life trying to make up for their different upbringings by becoming more wealthy, and Gatsby is eager to show Daisy how well-off he has become. 
Another symbol in The Great Gatsby is the green light. The light first appears at the end of chapter one when Nick sees Gatsby at the end of Gatsby's pier reaching out towards "a single green light". This light symbolizes new life and money, which for Gatsby, means Daisy. The green light also appears in the fifth chapter after Gatsby tells Daisy that her house is right across the Sound from his. He says that she always has a green light that burns all night at the end of her dock. The green light turned into the renewal of Gatsby and Daisy's friendship and possibly a rekindling of their prior relationship.
The third symbolic element is the Valley of Ashes. The Valley is the epitome of dull, mundane life. The other side of the Valley consists of a life where anything is possible. This is very similar to the difference between Gatsby's past and Gatsby's potential future with Daisy. Gatsby dreams of re-igniting Daisy's interest in him, just as one is almost revived as a person when traveling from the dismal Valley to the lively city of New York.
