The American Dream is defined as

"the ideal that every US citizen should have an equal opportunity to achieve success and prosperity through hard work, determination, and initiative."

It's called the "American Dream" because it is the national ethos of the United States (Wikipedia has a page on it). It's not that the U.S. invented being rich or that no-one else can achieve it, it is that Americans hold the belief in particularly high regard, as it's sort of culmination of the natural rights (life, liberty, pursuit of happiness, etc).
