O economic classes

Explanation:

There are wide varieties of economic inequality, most notably measured using the distribution of income (the amount of money people are paid) and the distribution of wealth (the amount of wealth people own). Besides economic inequality between countries or states, there are important types of economic inequality between different groups of people.[2]Important types of economic measurements focus on wealth, income, and consumption. There are many methods for measuring economic inequality,[3] the Gini coefficient being a widely used one. Another type of measure is the Inequality-adjusted Human Development Index, which is a statistic composite index that takes inequality into account.[4] Important concepts of equality include equity, equality of outcome, and equality of opportunity.

Research suggests that greater inequality hinders economic growth, and that land and human capital inequality reduce growth more than inequality of income.[5] Whereas globalization has reduced global inequality (between nations), it has increased inequality within nations.[6] Research has generally linked economic inequality to political instability, including democratic breakdown[7] and civil conflict.[8]
