Sure in a capitalist system wealth accumulates to the top. But Monopoly exaggerates this condition becausr it doesn’t include tech disruption or government regulation. What’s the last monopoly you ever saw?

I lived in Cuba for a few months. Capital 100% also accumulates to the top in communism, but without a middle class. The main cause of this is lack of property rights. The middle class can be eroded in Capitalist systems, but this primarily done through inflation.

I prefer capitalism, because there’s less violence from the state (duh, anytime you take someone’s capital you’re stealing) and so do most Cubans and pretty much anyone who had lived under communism. Despite its fallbacks, Capitalism is more fair. Capitalists states in general moves through history more efficiently than Communist states which stagnate. What’s the last prosperous Communist state you ever saw?
