concept of the american dream?
i need to write an essay about the concept of the American dream it needs to be three to four pages long. i need ideas to include in it and i dont know how to start it off.

The concept of the American dream is that if you work hard, regardless of class (what situation your parents raised you in), you can achieve your goals. Every American has the same opportunities, freedoms, and rights. If you’ve read any books like “Of Mice and Men” that pertain to the American dream, incorporate them. If you aren’t supposed to include books, completely ignore that last sentence. Talk about the public education system, women’s rights, Affirmative Action. Go research the Constitution and the Declaration of Independence and see what promises they made.
