I'd define the upper class economically as mostly those who have (had and still have) a large amount of inherited wealth, regardless of their current income, education, profession, or cultural associations. The United States for the most part does happen to lack a significantly sized upper class in this sense, though numerically the result is thus a quite large middle and unfortunately a somewhat distinct poor/lower class persisting across generations. Generally the middle class American Dream is kinda seen as to become part of this upper class for future generations; the line does blur a little for a first-generation person who becomes rich enough, as it is odd to think that Bill Gates wouldn't be upper class but his children would; however, he could be said to have a middle class background. Regardless, the upper class also maintains a very strong overrepresentation in politics and other public sphere endeavors.
