Cuba is a prime example of a completely isolated system, based entirely on Socialism. Every socialist system that exists today often has heavy trade with less socialist or even more socialist systems, helping to perpetuate and distort the reality of those systems.
Cuba however just cut funding for health care and education. So it makes me wonder, what country on this planet, could exist isolated as a socialist entity? Maybe China or maybe Russia, but that is about it.
At least Cuba, unlike most developed nations (not saying Cuba is) has the bravery to cut those welfare programs. Meanwhile the rest of the world plungers further into currency devaluation and bankruptcy.
Maybe, after all we could learn a thing or two from those commie bastards in Cuba?
