Then let's talk privilege. America's underclass is created not just by income inequality, but also by the collective belief by those not in the underclass that the underclass is worthless. If this were not the case, then they wouldn't continually create policies to keep them down.
Andrew Yang 2020 has policies that are inspired by what MLK promoted. The $1000 monthly "freedom dividend" will definitely be a game changer for poor minorities.
Income inequality is not restricted to minorities.
There are more white people living in poverty/prison than any other racial group.
