The reason why Cuba is a hell hole in the same way as the Soviet Union was a hell hole is not that it’s poor, consumer goods can only be bought at the black market at enormous prices, medical care and education are ridiculously bad, and the standards of hygiene are abysmally low.
All of this is insignificant compared to the real tragedy of Cuba (inherited, I remind you, from the USSR). The people’s soul had been murdered. All normal human instincts, impulses, values and connections have been broken. There is nothing but cynicism, cruelty, and indifference. Poverty can be overcome but how do you escape from the reality where doctors torture patients as a matter of course because it’s fun to do and where people are casually and mindlessly cruel to each other all day long just because they can?
There is nothing anybody can do except feel sorrow for the mindless destruction of what used to be a valuable, productive culture.
