Yes, there was corruption under Batista, however it was never this bad. Castro used the dissatisfaction amongst the poor Cubans to rise to power. By the way, Castro was never a 'socialist' he simply took up that philosophy because it eased his way into becoming a dictator. He probably would have been more right-leaning if the U.S. had accepted him, the more that he was rebuffed and scorned by Kennedy, the further left his view went. He found allegiance with an eager Soviet Union that was looking for an ally only 90 miles from U.S. soil during the peak of cold war tensions.
You're one of the few people that bring this up, fair play and who knows but I think that the US President of the time effectively snubbing him when he went over probably didn't help. Reap what you sow and all that.
There is such repression there currently, such fear that people don't say anything even remotely derogatory against the government while in public. It literally permeates through society, who by the way aren't even allowed to have access to a great many things that a tourist can enjoy. My parents wanted to stay at a hotel during their stay in Veradero Beach, they wouldn't allow their Cuban relatives to stay in a room so they ended up renting someone house for the night.
That was the case, that Cubans weren't allowed to stay in hotels prior to two years ago. That's now changed. But it's the way it was, the hotels were for the tourism.
Batista was corrupt however the people were free, and the country as a whole was prospering (although Batista didn't address the poor as he should have). Cuba at that time was amongst the strongest of the spanish-speaking South/Central American and Caribbean countries. Now they are amongst the very poorest.
It depends how you determine wealth, by money? Tut tut, you dirty capitalist pigdog. I determine it by the quality of life and the general happiness of the public there. Like I mentioned above, healthcare, education and very low crime rate help considerably. The people are generally happy, of course you could always be happier and the recession is affecting the country as anywhere but people are generally happy. Who wouldn't be, it's a beautiful country. The one grumble you do hear is about the restriction on travel but on the whole they don't have it too bad.
