The American Dream is the national ethos of the United States, that every person has the freedom and opportunity to succeed and attain a better life. The phrase was popularized by James Truslow Adams during the Great Depression in 1931, and has had different meanings over time. Originally, the emphasis was on democracy, liberty and equality, but more recently has been on achieving material wealth and upward mobility.

Social mobility is the movement of individuals, families, households or other categories of people within or between social strata in a society. It is a change in social status relative to one's current social location within a given society. This movement occurs between layers or tiers in an open system of social stratification. Open stratification systems are those in which at least some value is given to achieved status characteristics in a society. The movement can be in a downward or upward direction. Markers for social mobility such as education and class, are used to predict, discuss and learn more about an individual or a group's mobility in society.
