Thank you so much.
From the settlers who first arrived to America, to the Confederates and the modern day citizens, Americans are all in pursuit of one thing; the American Dream. It is a dream of equality, opportunity, prosperity and love. As promised in the United States Declaration of Independence, every man has “unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness” (US 1776). From this phrase, every member of the United States is guaranteed an equal chance at achieving the American Dream. This united vision is what comes under scrutiny in F. Scott Fitzgerald’s The Great Gatsby. An examination of this classic American novel will show that in the 1920’s, the American Dream had stagnated into a state of moral decay due to pure greed, crass materialism and self-indulgence as evidenced by the three main characters: Jay Gatsby, and Daisy and Tom Buchannan.
Jay Gatsby, Fitzgerald’s title character, is a clear example of the tainted American Dream in the 1920’s. He represented the common man in this post-war era with his rise from rags to riches. Like the common man, his greed and thirst for a life of extreme luxury led to his moral decadence. Gatsby came from a poor family in North Dakota. After having a taste of the life of the wealthy, he is fixated with obtaining the glamorous, luxurious lifestyle. Along with the lifestyle, he dreams of Daisy Buchannan, who represents everything he desires to obtain. He disowned his family and their name in search of a new identity. Instead of achieving this new persona with honest hard work, Gatsby earned his fortunes from the illegal sale of bootleg alcohol. “He and this Wolfshiem bought up a lot of side-street drug-stores here and in Chicago and sold grain alcohol over the counter.” explained Toms on the origin of Gatsby’s fortune and Gatsby answers “What about it?” confirming that the rumour is true (Fitzgerald 107). With his corrupted fortune, the final piece of his decayed idea of the American Dream was Daisy Buchannan. Gatsby loved Daisy since the day they met and to him, she represented all that was wealthy and extravagant. As Nick explained when he and Daisy visited Gatsby mansion, Gatsby “hadn’t once ceased looking at Daisy, and [Nick] think[s] [Gatsby] revalued everything in his house according to the measure of response it drew from her well-loved eyes.” (Fitzgerald 73). Gatsby used materialism to win Daisy over and knowingly led her to infidelity. From his fraudulently earned lifestyle to his sinful actions to find love, Jay Gatsby’s journey to his corrupt American Dream was full of greed, materialism and moral decline.
Daisy Buchannan poisoned the American Dream with her beliefs in materialism, inequality and superiority of the upper class. She was in constant pursuit of wealth and simply wowed by possessions and status. As a young lady, she engaged in a love affair with Gatsby, who was poor at the time and tricked her into thinking otherwise. Daisy captured Gatsby’s heart. After he was sent away to war, he remained faithful to her until they met again five years later, despite her marriage to Tom. Daisy however “began to move again with the seasons; suddenly she was again keeping half a dozen dates a day with half a dozen men. …She wanted her life shaped…immediately- and the decisions must be made by some force- of love, of money, or unquestionable practicality- that was close at hand.” (Fitzgerald 120). Clearly the decisions was not out of love as on her wedding day, Daisy was found drunk saying “Tell’em all Daisy changes her mind.” (Fitzgerald 61). Upon being reunited with Gatsby, she was instantly wowed by his material possessions, crying over his fancy shirts and enormous home. Daisy’s crass materialism trumps any feelings of love that she may have. Lastly, Daisy places herself as a superior, above the common man and above the law. She is “gleaming like silver, safe and proud above the hot struggles of the poor” in Nick’s opinion (Fitzgerald 119). She literally gets away with the murder of Myrtle and suffers no consequence. As Nick Carraway describes “They were careless people, Tom and Daisy — they smashed up things and creatures and then retreated back into their money or their vast carelessness, or whatever it was that kept them together, and let other people clean up the mess they had made.” (Fitzgerald 142). Daisy abolished the vision of equality, opportunity and love, promised by the American Dream and permanently ending the pursuit of this dream for Myrtle, Wilson and Gatsby.
Leaving for work now, so not a lot of time to elaborate…
In the first paragraph I find your parallel of the "American Dream" and "The Pursuit of Happiness" a little confusing.
I think maybe you should choose one over the other, or at least connect them better somehow.
Verify proper capitalization: "unalienable Rights" and "… pursuit of Happiness" can’t be right.
I think either both caps or neither caps, but not mixed (probably both caps would be right.)
Change "members" to "citizens" in the first paragraph.
Using the word ‘members’ makes it sound like you’re talking about states, not people.
In the third paragraph I’m a little unclear on Daisy’s poisoning of the American Dream.
That’s a lot of responsibility / blame to put on one person 
Perhaps she poisoned *someone’s* American Dream, but not "The American Dream".
But I thought it was well written.
Wish I had time to read the whole essay.
