You either deliberately choose to ignore all the atrocities that Lenin, Stalin, and subsequent Soviet leaders committed against Soviet citizens and the complete lack of freedom, or are completely ignorant of the topic.
"But the previous guy did it too!" is not an argument. Also, the famines caused by the Soviet policies are unmatchable in World history, especially considering the timeframe.
Not to speak about the many violations of basic human rights, such as the abolition of private property.
Life was hard for most people around the globe at the time of the Russian revolution, however, those countries that chose democracy and capitalism managed to improve considerably, while those who chose Marxism have today much to regret.
One might argue that Marxism can't be possibly blamed for this, but (and this is something many have a hard time understanding) Marxism does inevitably lead to these conditions. Karl Popper's "The Open Society and Its Enemies" is a good start at why.

Comparing Cuba with Haiti is the equivalent of comparing Southern Europe with Northen Africa. Very close to each other but still two worlds apart.
Pre-Castro Cuba was, by most standards, far ahead most of Latin America and the rest of the world. [1][2]
