Economic inequality (also known as the gap between rich and poor, income inequality, wealth disparity, or wealth and income differences) comprises disparities in the distribution of economic assets (wealth) and income within or between populations or individuals. The term typically refers to inequality among individuals and groups within a society, but can also refer to inequality among countries. The issue of economic inequality is related to the ideas of equity, equality of outcome, and equality of opportunity.
Observers differ on both the morality and utility of inequality, whether, and/or how much inequality is necessary in society and how it can be affected. It has been praised as necessary and beneficial, and attacked as a growing social problem. Early studies suggesting that greater equality inhibits growth have been shown to be flawed because they did not account for the many years it can take equality changes to manifest in growth changes, and greater equality has been conclusively shown to cause growth.
Economic inequality varies between societies and historical periods; between economic structures or systems (for example, capitalism or socialism), ongoing or past wars, and differences in individuals' abilities to create wealth are all involved in the creation of economic inequality. Economic inequality can refer to cross sectional descriptions of the income or wealth at any particular period, and to the lifetime income and wealth over longer periods of time. There are various numerical indices for measuring economic inequality. A prominent one is the Gini coefficient, but there are also many other methods.

Famous quotes containing the words economic and/or inequality:
“Postmodernism is, almost by definition, a transitional cusp of social, cultural, economic and ideological history when modernism’s high-minded principles and preoccupations have ceased to function, but before they have been replaced with a totally new system of values. It represents a moment of suspension before the batteries are recharged for the new millennium, an acknowledgment that preceding the future is a strange and hybrid interregnum that might be called the last gasp of the past.”
—Gilbert Adair, British author, critic. Sunday Times: Books (London, April 21, 1991)
“The doctrine of equality!... But there exists no more poisonous poison: for it seems to be preached by justice itself, while it is the end of justice.... “Equality for equals, inequality for unequals”Mthat would be the true voice of justice: and, what follows from it, “Never make equal what is unequal.””
—Friedrich Nietzsche (1844–1900)
