[3][4][5] The term enlightened self-interest has been criticized as a mere ideological or semantic device of neoclassical economic theory to justify this type of behavior.
[6] In contrast to enlightened self-interest is simple greed, or the concept of "unenlightened self-interest", in which it is argued that when most or all persons act according to their own myopic selfishness, the group suffers loss as a result of conflict, decreased efficiency and productivity because of lack of cooperation, and the increased expense each individual pays for the protection of their own interests.
Some individuals might profit, in a material sense, from a philosophy of greed, but it is believed by proponents of enlightened self-interest that these individuals constitute a small minority and that the large majority of persons can expect to experience a net personal loss from a philosophy of simple unenlightened selfishness.
An individual may choose to forsake pursuing immediate gratification by supporting and not interfering with others' pursuit of self-interest.
[9] Rational selfishness is a term generally related to Ayn Rand's Objectivist philosophy, which refers to a person's efforts to look after their own well-being, to cultivate the self, and achieve goals for the good of the self.
