The American Dream, or the belief that through hard work all things can be accomplished, is deeply rooted in the United States’ psyche. Although first coined in 1931 by James Truslow Adams in his book The Epic of America, this sentiment can be seen throughout American political, historical and fictional writings from the preamble of the Declaration of Independence to F. Scott Fitzgerald’s The Great Gatsby.
However, according to the St. Louis Federal Reserve, the percentage of middle income earners (the middle 50%-90% of income earners) fell from 42% in 1989 to 37% in 2016 (Kent & Ricketts, 2019). The numbers are starker when analyzed by race. In 2016, “the average wealth of white households … was seven times the average wealth of black households and five times of Hispanic households” (Brainard, 2019).
As the middle class shrinks and consumer debt, education and healthcare costs increase, a national conversation has focused on the wealth gap within America and the realities of the American Dream (Brainard, 2019; Andriotis & Brown, 2019).
Academic research has and continues to heavily investigate the wealth gap (Piketty & Saez, 2003; Saez & Zucman, 2016; Chetty et al., 2017; Autor, 2014). While many facets affect the wealth gap, literature has identified income mobility and income inequality as two factors with significant influence.
Income mobility, the ability to change economic status, is a crucial component of generating wealth. Research, however, indicates that income mobility in the United States has decreased, especially for certain geographic regions and populations (Lefgren, Pope, & Sims, 2019; Chetty et al., 2017; Durlauf & Seshadri, 2018). Chetty et al. (2017) found that “absolute income mobility has fallen across the entire income distribution, with the largest decline for families in the middle class.” Compared to Canada, which has a similar national philosophy of the American Dream, the United States has significantly lower intergenerational income mobility (Connolly, Corak, & Haeck, 2019).
Literature has noted that the level of intergenerational mobility varies substantially across the United States. Although some areas of the country have high levels of income mobility, other areas have income mobility levels lower than any developed country, given the available data. While income mobility levels vary within regions, as a whole, the Southeast region experiences the lowest upward income mobility, while the Great Plains, West Coast and Northeast have high income mobility. In addition, areas with high income mobility tend to have “less residential segregation, less income inequality, better primary schools, greater social capital and greater family stability” (Chetty, Hendren, Kline, & Saez, 2014).
According to U.S. Census Bureau data, income inequality has steadily increased for the last 50 years, reaching an all-time high in the most recent calculations. In addition, since the late 1970s, the majority of wealth accumulation has been within the top 10% of earners (Saez & Zucman, 2016).
