> Research has generally linked economic inequality to political and social instability, including revolution, democratic breakdown and civil conflict.[5][10][11][12] Research suggests that greater inequality hinders economic growth and macroeconomic stability, and that land and human capital inequality reduce growth more than inequality of income.[5][13] Inequality is at the center stage of economic policy debate across the globe, as government tax and spending policies have significant effects on income distribution.[5] In advanced economies, taxes and transfers decrease income inequality by one-third, with most of this being achieved via public social spending (such as pensions and family benefits).[5] While the "optimum" amount of economic inequality is widely debated, there is a near-universal belief that complete economic equality (Gini of zero) would be undesirable and unachieveable.[14]: 1 just from wikipedia: https://en.wikipedia.org/wiki/Economic_inequality https://en.wikipedia.org/wiki/Economic_inequality
