Good afternoon.
The Great Gatsby is a very important book in American literature, and as such there are numerous study guides, online and in print, that can help you with this essay. I suggest you find a good, comprehensive study guide that can help you with the rest of this course.
You can begin this essay by going through the text and picking out different instances in the text that can be interpreted from these two perspectives. For instance, Gatsby's house. It is a large mansion, an ode to his wealth and success. On the other hand, the wealth and success that afforded him this property was acquired by less than scrupulous means, therefore it can be seen as corrupt, even disgusting.
Once you have several items from the text, you can look at them from both points of view, creating almost a compare/contrast outline. That will give you a good start.
I wish you the best of luck!
