your statistics are BS. First of all, 80% of the population in Cuba was literate under Batista and the presidents before him. Cuba was ranked 4th in Latin America. I'm guessing you pulled the other statistics out of you ass as well.
A portion of the Batista dictatorship of Cuba was of course shown in the Godfather part II. The sequence involves Michael Corleone(Al Pacino) trying to invest the Corleone family money into the casinos in Havana in the late 1950's. This of course is during the time of the Cuban revolution. There is a scene when Michael, Hyman Roth(Lee Strasberg who's character was based on Jewish gangster, Meyer Lansky) attend a business meeting that is conducted by then Cuban dictator Flugencio Batista(who was also a friend of Meyer Lansky). After the meeting, Michael along with his bodyguard and Johnny Ola(Dominic Chianese of the "Sopranos") are driving through a street in Havana and run into an arrest in which one of the men who was being arrested, grabs the captain who was in command of the soldiers/police and places him inside the backseat of a car in which he gets on top of the captain and commits a murder/suicide by having a grenade explode that was hidden in a pocket of his jacket which of course kills both the captain and the man. Of course before this murder/suicide, the man shouts, "Viva Fidel." After the incident, Michael discusses it at Hyman Roth's birthday party. He ends the discussion by stating that the Cuban soldiers are paid to fight while the Cuban rebels aren't,which will cause the Rebels to win the revolution. Johnny Ola's response was that the Cuban rebels were lunatics while Hyman Roth's response was that being a rebel was basically in a Cuban's blood. That last statement relates to the many revolts in Cuba that stemmed from the 1890's when Cuba began to fight for its independence from Spain. Eventually this sequence of the movie ends with the New Year's festivities of 1958/1959 which of course causes Batista to resign from power and leads to the Communist dictatorship of that country by Fidel Castro which has pretty much ruined that country for over 50 years. Of course, riots break out in the streets of Havana at the very ending of this sequence of GF II. Although GF II and the Motorcycle Diaries are totally different movies, I just felt that I had to bring this all up because I felt that it related to this post.
You have no point. Fidel Castro did absolutely nothing to ruin Cuba's economy other that refusing to suck the USA off. The USSR backed him and when they fell, the USA only strengthened their embargo; that compounded with the fact that Cuba has no natural resources to sell (one of their greatest exports is doctors), means that they have no chance in hell if the USA is keeping them poor.
I guess if you cause the Cuban Missile Crisis, people do not forget...
