Income inequality 

A naturally occurring part of civilization; just like education inequality (e.g. not everyone has PhDs), hair color inequality (not everyone is blond) and location inequality (not everyone lives in a city or a two-story house).
Often used by leftists, moonbats, and the Obama Administration and like-minded as class warfare to drum up division and anger among citizens.

Malcolm got his MBA after five years of work experience and is now earning $150k a year at his new job. Tina dropped out of college, where her major was Women's Studies, and is stuck with a $30k a year job. Income inequality!

Wealth Inequality 

When a CEO earns more than 300 times in a day what many of their workers earn in a year, or when the top 0.1% owns as much as the bottom 90% of the population.

The immoral wealth inequality is proof of pure hypocrisy by billionaires and CEOs, who never fail to point out that they’ll give away most of the wealth after their last heartbeat.

Vaccine Inequality 

When mostly corrupt or undemocratic developing countries blame the rich nations for hoarding the vaccines and expect them to fund their vaccination needs on moral grounds, as few could afford to buy them for their own citizens—when beggars become choosers and accusers, and donors are viewed as hoarders and betrayers.

WHO argues that vaccine inequality threatens global Covid-19 recovery, but avoids to address the root causes for the poor health systems plaguing most developing nations.
