And do note that Puerto Rico result. That Caribbean island remained under that American domination, that cruel capitalism and the chaos of markets. It was never enriched by the scientific planning of socialism. And living standards soared by a factor of 4 while those in Cuba stagnated for 5 decades. And the Cuban system justified itself by freeing Cuba from such American hegemony.
For that Fidel Castro should not be forgiven.
We also need to heed this lesson. Non-market economic systems do not work. We do only have that spectrum available to us, laissez faire all the way to social democracy. Socialism, not even once people, not even once.
