What is a common belief associated with the American Dream in the context of social stratification?

A common belief associated with the American Dream is that anyone, regardless of their background, can achieve success and prosperity through hard work and determination. This idea suggests that people can rise above their current social class and improve their lives if they put in enough effort. However, in reality, social stratification often makes it difficult for many individuals to access the same opportunities. For example, someone born into a low-income family might face challenges like limited educational resources, which can hinder their ability to pursue higher-paying jobs. Thus, while the American Dream promotes the idea of equal opportunity, social stratification can create barriers that make it harder for some people to achieve that dream.
