unequal distribution of wealth is the underlying issue, so essentially they are suggesting a progressive tax system whereby higher earners are taxed at a higher rate. Which allows the government to redistribute that wealth towards poorer areas of society whilst not impacting significantly on the living standards of the higher earner.

Well stated. All of the arguments above amount to "sure inequality is happening, but that's just capitalism so what can be done?" This.

Inequality.

The problem is, nearly never, access to resources: modern society (including in poor countries) puts necessary resources (food, clothing, shelter and even transportation) available to all at a very small price. Our material needs are 100% guaranteed.

The problem is that most of the goods that modern society produces are unavailable for most of the population. By reducing inequality, we could improve life quality for the masses.

I was asking specifically about the WC example, not real life.
