How are education and the American dream related?

The idea behind the American Dream is that anything that you can and want to reach/do, you will be able to, if you work hard enough to reach that goal. In most cases that means you need some sort of an education to either do what you want or to deal with the people/organizations in the real world. If you don't have at least a basic education that becomes impossible and then without amazing luck, your dream is stopped by red tape. Your dreams are limitless if you are willing to do the work.
