Economic inequality refers to differences in wealth, income, and assets between individuals and populations. The document discusses several key points about economic inequality:
1) It is a significant global issue as the world's wealth is unevenly distributed, with the richest 1% owning over 40% of global wealth while the poorest half own barely 1%.
2) Economic inequality is measured using the Gini coefficient, which calculates a country's wealth distribution on a scale of 0 to 1.
3) Economic inequality relates to and exacerbates many other social problems like poverty, lack of access to education and healthcare, gender inequality, and crime. It persists due to power imbalances that public policies and the economic system reinforce.
