"the cuban medical system is well-documented as extremely good". Sure it is. Based on statistics provided by the Cuban government, without no independent verification. A bit like the statistics that showed East Germany was one of the strongst economies on earth.Til the Wall Fell and the Regime collapssed. Then the truth came out. Broke, in debt, polluted beyond belief, supported by bank loans,West Germany, and even huge payments for each dissident arrested and allowed to cross to West Germany.Very lucrative it was. 

The statistics of a totalitarian regime are not worth the paper they are printed on.
