The American middle class during the post-war period helped the country to experience high levels of economic growth which was mainly driven by strong consumer demand. The social structure of American society dramatically changed because former military servicemen were offered affordable housing loans which made it easy for them to settle down and start families. Besides, there was a high demand for workers because many industries were keen to take advantage of thriving economic conditions in the country. The industrial, finance and service sectors of the economy grew at a faster rate compared to the agricultural sector which was the bedrock of the southern economy. This resulted in economic and political inequalities which were mainly driven by poor racial and social class politics. As a result, this increased the clamor for reforms in some segments of the population demanding equal social, racial and gender rights.

Some segments of the population did not experience benefits that resulted from high levels of economic prosperity in the country. For instance, African Americans and other minority racial groups took part in the civil rights movement to demand for greater social, political and economic equality. More importantly, the government was forced to carry out major legal changes to address racial segregation laws which had been enacted at the beginning of the 20th century. In the 1960s, the country experienced high levels of liberalism which led to an increase in social and political reforms. Many young people became rebellious and they embraced new forms of self-expression and this resulted in a cultural revolution. However, in the last two decades, the role of the middle class in America has become less influential due to a reduction in standards of living. Many corporate firms have restructured their operations and this has reduced the number of jobs in the country.
