Portrait of a Woman Suffering from Obsessive Envy; ThÃ©odore GÃ©ricault.

Greed, also known as Avarice, is an inordinate or insatiable longing for unneeded excess, especially for excess wealth, status, power, or food. As a secular psychological concept, greed is an inordinate desire to acquire or possess more than one needs. The degree of inordinance is related to the inability to control the reformulation of wants once desired needs are eliminated. Erich Fromm described greed as a bottomless pit which exhausts the person in an endless effort to satisfy the need without ever reaching satisfaction. It is typically used to criticize those who seek excessive material wealth, although it may apply to the need to feel more excessively moral, social, or otherwise better than someone else.
