Even though I absolutely love Michael Moore's documentaries, I found the part of his film Sicko where he talks about the state of medical care system in Cuba simply disgusting and extremely manipulative.
I've been to Cuba several times and I have to say that it mimics the sorry state of the Soviet medical care system in a very scary way. Of course, if you show up as a famous American film director surrounded by video cameras, you get an excellent level of care. If, however, you come as a simple tourist, be prepared to be refused care even if you are in real pain and are prepared to pay a lot to get help. You will be dismissed in a rude way and denied help.
Of course, if you show up as a Cuban citizen, then everything gets even worse. The government decides the minimal level of care you deserve, and you shouldn't hope to get anything above that. A woman who suffers from asthma told me that she is allotted a certain number of inhalers per year and can't get more even though she really needs them. An inhaler costs between $40-60 on the black market, so she is reduced to begging tourists for money or inhalers.
Those who want to support Cuba no mattter what will, without a doubt, claim that this is the result of the embargo. This view of Cuba's problems as being all due to the embargo fails to take into account the similarities between what happens in Cuba and the state of affairs in the Soviet Union. Soviet medical care was part of the state's repressive apparatus aimed at cowing people into submission. We are most vulnerable when we are sick and in pain. The goal of such systems id to make the pain just tolerable enough. If we are always just a little sick and helpless, we will not be likely to rebel.
