the american economy is called a mixed system because
Mixed economy Economies ranging from the United States[5][6] to Cuba[7] have been catalogued as mixed economies. The term is also used to describe the economies of countries which are referred to as welfare states, such as the Nordic countries.[8][9] Governments in mixed economies often provide environmental protection, maintenance of employment standards, a standardized welfare system, and maintenance of competition.
Social class in the United States Social class in the United States is a controversial issue, having many competing definitions, models, and even disagreements over its very existence.[1] Many Americans believe in a simple three-class model that includes the "rich", the "middle class", and the "poor". More complex models that have been proposed describe as many as a dozen class levels;[2][3] while still others deny the very existence, in the European sense, of "social class" in American society.[4] Most definitions of class structure group people according to wealth, income, education, type of occupation, and membership in a specific subculture or social network. Most of the social classes entirely ignore the existence of parallel Black, Hispanic and minorities societies.
