You're missing something essential, Ivo.
Guevara was a unique revolutionary in that the trappings of post-revolutionary power were not for him.
There was another side to his career, as post-revolutionary Minister of Mines - if you travel to their flagship Nickel mine in Moa, you will see the Che Guevara mine, and if you enter their buildings you are likely to see a large picture of a reasonably smartly-dressed Che, sitting and listening intently to one of their engineers, cigar in hand. He is still regarded as an inspiration to these people, not just as a revolutionary. But he left all this to run a rag-tag army in the ungovernable Congo, and then again under miserable circumstances on his final self-inspired mission in the corrupt cesspools of South America.
Despite the awful image worn by equally awful youth, this is a man who has earned respect, including mine.

Your asides about the economic condition of Cuba are also incorrect and misguided. But I have no space for that!
