This seems like a tough assignment, but you can do it. It helps to read an analysis online. That is not cheating; it's using literary analysis to help you appreciate the stuff, like you are supposed to do. So google the title with the word: analysis
Google the title also with the word: review
Read the way its themes are explained, and really get interested. The key to life is right here if you know where to look.
When you are done with that, google this: america's economy
You are going to have to read a lot of articles, like 6 or something. Write a paragraph about each. It is not hard to write a paragraph about the main idea of an article. Do that for 6 articles, and compare each article to the story.
