Educational attainment
Educational attainment is one of the primary indicators of social class in the United States. While the American social class system is a vaguely defined concept with many contradicting theories, educational attainment emerges as one of the top assessments of social class. Not only is a high educational attainment a status symbol by itself, but it is also very closely related to the other two main indicators of social class: occupation and income. A graduate degree and the roughly seven to eight years of post-secondary education serve as the main requirement for entering the "professions" and becoming part of the professional middle class.
