It all depends on which American Dream you're talking about.
When I Google the American Dream, a website defines it as "...the belief that anyone, regardless of where they were born or what class they were born into, can attain their own version of success in a society where upward mobility is possible for everyone."
This isn't true. It just isn't.
In a perfect world, the dream itself doesn't change, but the rules we have in place to keep specific groups of people lower than others do. I personally believe it can't. I do think it is achievable without hard work; specifically if you aren't a minority, and born into a rich family. But, this is just my personal opinion.
The Scarlet Ibis, the older brother loves his younger brother. He teaches him to walk, to play, etc. Then, one day the older a younger brother walk to a tree and the older brother gets angry and runs away. The younger brother is ill and can't run. When the younger brother attempts to run after his older brother, he runs out of air and dies. The older brother feels horrible and the younger brother dying reminded the older brother of the scarlet ibis that had died earlier in the story. Both were helpless.
