Taking good care of the slaves

Regarding the Castro dictatorship's accomplishments, it doesn't really have "a model health and educational system". It's simply a system intended to maintain a slave population working for its owners, mostly as government employees or in menial jobs servicing foreign tourists, as prostitutes, waiters, etc

I must remind you I lived in Cuba under the Castro dictatorship, my father was a physician, and my mom was a nurse. My understanding was that it provided a fairly good basic preventive system, mediocre if the sickness was serious, and extremely high quality for the upper dictatorship caste. 

The educational system I attended was very strict and somewhat stratified. We were tested with what was called "Pruebas de Nivel" (level tests), and those who didn't pass became repeaters. We were told repeaters would eventually be sent to work in farms if they didn't straighten out. I had a first cousin who was sent to one of those farms, but in his case it was because he was homosexual (he got caught when he was sixteen years old). 

Entering high school required that one have the right political pedigree, and this was even stricter regarding entry to college. In my case I got in trouble with the school authorities debating over the lack of food for lunch (it was more of a misunderstanding but they were extremely harsh). At that point I realized I had no future living as a slave in a communist dictatorship and left on my own. 

I can vouch that the education I got in Cuba was good enough that, once I managed to get to the USA, I made the honor roll within the year, and eventually graduated without any problems, in spite of having missed over a year of schooling. 

What many of you don't understand is that the system is designed to create obedient slaves who are in basic good health. It's a pragmatic approach any intelligent slave owner uses, it's simply taking care of the animal farm.
