This is clearly an issue. The more unequal the spread of wealth the more problems.
Other way around.
Equal spread of wealth = everyone is poor, downtrodden, and live short brutish lives.
The more unequal the spread of wealth the more prosperous a society is for everyone, even the people at the bottom.
No, maybe I was to brief in my wording. I'm not saying wealth has to be spread exactly equally for everything to be perfect, only that grossly unequal societies tend to have problems because of the gross inequality (see my video and countless other evidence). It is definitely possible that a really unequal society can be better for the poor than a more equal society, but not if every other factor is equal between those societies.
Look, complete equality should not be the goal of any society, but ignoring gross wealth inequality as an issue is simply not realistic and not backed by science.
