Several posts are at the above link about Cuban hospitals from people who had been patients. Other than the medical staff who seem to be well-trained and making do with very limited resources, I doubt most of the leftists would want to experience Cuban medical services (which are only free to Cubans).
I wonder why we don’t see these romanticized delusional stories about North Korea?
We did see it about the Soviets, especially from the New York Times in the 1920-30s.
