I don't agree. The people that invented capitalism invented capitalism. Other people wouldn't invent the same sytem. We couldn't yet know if the economic rationalism required to prefigire comunism would be more or less likely with the new world being essentially off limits for resource extraction. I would think thst process would be faster and less totalizing in the senario of a depopulated old world. Which if it works would represents a massive savings in life lost over time. Since europe does go on to colonize and kill huge numbers of people in the old world as well.

If it does not work. We can just go back and undo the change we changed.
