American upper class
This term is applied to a wide array of elite groups existing in the United States of America. The term commonly includes the so-called "blue bloods" (multi-generational wealth combined with leadership of high society) such as the Astor or Roosevelt families. There is disagreement over whether the "nouveau riche" should be included as members of the upper class or whether this term should exclusively be used for established families. Twentieth century sociologist W. Lloyd Warner divided the upper class into two sections: the "upper-upper class" and "lower-upper class" . The former includes established upper-class families while the latter includes those with great wealth. As there is no defined lower threshold for the upper class it is difficult, if not outright impossible, to determine the exact number or percentage of American households that could be identified as being members of the upper-class(es).
Income and wealth statistics may serve as a helpful guideline as they can be measured in a more objective manner. In 2005, approximately one and a half percent (1.5%) of households in the United States had incomes exceeding $250,000 with the top 5% having incomes exceeding $157,000.[19] Furthermore only 2.6% of households held assets (excluding home equity) of more than one-million dollars. One could therefore fall under the assumption that less than five percent of American society are members of rich households. The richest 1% of the American population owns as much as the combined wealth of the bottom 90%, or perhaps even more.
Yet another important feature of the upper class is that of inherited privilege. While most Americans, including those in the upper-middle class need to actively maintain their status, upper class persons do not need to work in order to maintain their status. Status tends to be passed on from generation to generation without each generation having to re-certify its status. Overall, the upper class is
