There are many alternative ways to distribute wealth, Cuban communism being only one of them. Capitalists would like us to believe in a false dichotomy between democratic capitalism and totalitarian communism.

Instead of Cuba, why not point to the sovereign wealth funds of Norway or Alaska? Or farmers' co-ops in the American midwest? Or just the generally successful democratic socialist countries in Europe where standard of living is better by many measures than in the US?

None of those are perfect, but they show that commerce and wealth distribution don't have to be purely "it takes money to make money".
