King, you are baiting people, but I will briefly rise to it.
Castro overthrew a failed dictatorship which denied people for the benefit of itself and a rich business class, he replaced it with a tyranny of murder, imprisonment, and torture.
The billpayers were the Cuban people. The argument they are better off is specious at best. Assuming you were right, which I do not believe to be the case, it is improvement with a collar and chain attached.
I doubt you would accept a golden bowl with the denial of basic freedoms. I don't believe the Cuban people would if they really had the chance to vote.
I won't bother with addressing the tiered Cuban medical system, or their free universal education, neither of which is what "great minds" like Michael Moore would have us believe.
