The inequalities of wealth and fortune form a central part of the human condition, and these over time have been a constant source of social unease. Whether they should be praised and preserved or endured or corrected is an issue that produces uniform discord. One source of this difficulty in analysis stems from the possible ways in which these persistent inequalities arise. It is easy to condemn any differences in wealth created by the victor's expropriation of the vanquished's honest toil. It is far more difficult to condemn those identical differences when they are attributable to the thrift and foresight of the successful relative to the laziness or self-destructiveness of the impoverished. Furthermore, most find it morally ambiguous how best to respond to differences between persons that are the result of luck or chance, such that they do not reflect positively or negatively on either the character of those who have done well or those who have done poorly.
