Overclass is a recent and pejorative[1][2] term for the most powerful group in a social hierarchy.
Users of the term generally imply excessive and unjust privilege and exploitation of the rest of society.
[3][4][5] The word is fairly recent: the Oxford English Dictionary included it only in December 2004.
Both are in an adversarial posture toward the great majority of Americans, the overclass by virtue of ambition and unbounded self-esteem, the underclass by virtue of social incompetence and anomie.
[8] Perhaps the most commonly agreed-upon "overclass" consists of leaders in international business, finance and the arms trade.
