Capitalism is just really good at telling people the reason they are poor is because they just don't work as hard as the elites
capitalism can work with say 99% tax on estate on death. No trust funds. Tax on wealth above a certain point. Rule of law with sharp teeth. Proper investment in education. Proper anti monopoly so all large corporations gets broken up to avoid their power consolidation...
communism is dictatorship in disguise.
then you have old style feudalism with aristocracy.
anything else?
All capitalist.
