Middle class is a group of people between the upper and lower classes in a society. Many people in the middle class share similar levels of education, income, wealth, and power. For example, the majority of middle-class people have at least a high-school education and a comfortable standard of living. People in the middle class work for a living and do not inherit great wealth, but they can hold almost any occupation. People who consider themselves middle class often share certain personality traits, too, such as individualism, self-motivation, industriousness, and strict moral standards.
