Staying with the idea of the thread, I found a quick, simple half page article on Cuba and Communism if anybody is interested. Castro overthrew a corrupt regime in '59, and to survive as a country they needed to adopt a political system that sacrificed the good of the individual for the good of the whole. With few natural resources and trade cut off from 90% of the world, capitalism couldn't work if he wanted to feed the citizens of Cuba. Also, he did institute national education and healthcare and they have survived.
Did this happen at the expense of human rights violations and autocratic rule? Yeah. But think - there is a reason corporations don't operate as democracies, there may be situations that one leader is required...
