I don't think you understand how income inequality works.
If you think it's a problem in the west then you have no idea how it works in developing nations.
The top 20% of the income bracket in Germany makes only 4.2 more on average than the bottom 20% in China it's 20-30, in many African countries it's 40-50.
The average is influenced by outliers, so in cases with high income inequality, it does not necessarily represent central tendency well. In such cases, the median (or other percentiles) can be used for more accurate representations of economic power.
