The "American Dream" is a national ethos in the United States that suggests anyone, regardless of their background, can achieve success and prosperity through hard work and determination. It often emphasizes the importance of individualism, freedom, and the pursuit of happiness, encouraging people to strive for a better life. Historically, the concept has been linked to opportunities such as homeownership, education, and upward mobility. It is often symbolized by the idea of the land of opportunity, where immigrants and citizens alike can pursue their goals and improve their circumstances, contributing to the nation's growth and diversity.
