 There are two main lines of defensive argumentation. The most influential is Adam Smith’s well-known argument about the positive side-effects of a self-interested pursuit of profits: although the baker and brewer only aim at their own respective good, Smith suggested, they are “led by an invisible hand” to at the same time promote the public good (Smith 1776, see also Mandeville 1732). This argument is typically viewed as a consequentialist vindication of the profit motive (see also  consequentialism):  positive societal effects can morally outweigh the possible shortcomings in individual virtue (Flew 1976).
