Unfalsifiable claim since we can't predict what could have been if things had been done completely differently. But, Cuba distributes wealth more justly, so where are all the innovators coming out of Cuba? Where is the quality of life?
In fact, there are undoubtedly more Cubans building things, inventing things, and performing valuable services in the US than there are in Cuba, because in the US we allow you to be rewarded for providing something valuable to society.
If you turn the country into a wealth-redistribution paradise, the smartest people will all go somewhere else, because people don't want to work purely "For the Motherland." They want to help their country and provide for their own family's wellbeing too.
History has provided examples of this, but to top off their failure to deliver higher quality of life, most nations that established themselves explicitly to ensure fair distribution of wealth couldn't even restrain their elites from gorging at the "communal" trough to the point the commoners suffered great deprivation.
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".
