Do you think calling me names is adding to the point you are trying to make, or detracting from it? Also, someone else made the claim that 100s of millions were killed by communism (though they weren't wrong). You're replying to the wrong person. I'm getting the impression you are very young, and - once again - that you have not been to or even talked to people from Cuba. I'm not trying to have an Internet slap fight with you, but you should really look into Cuban society and history. If you don't have the opportunity to actually go there or talk to Cubans, I recommend Cuba Beyond the Beach. It's written by a Canadian professor who lived many years there. It is not political, but will give you insight into what life is like there. You might curb claims like "Cuba has one of the best societies on the planet."
To say "economic success is only a measure of happiness under capitalism" is something that only someone who has lived a life of wealth and luxury will ever say. I say this as someone who lived under a communist regime, and has seen awful people both there and here. You could not be more wrong - the most materialistic people are often the poorest, or those who were the poorest, because they know the value of what they don't have. But I don't want to be antagonistic toward you - I'm just trying to point out why I think you're wrong, not that I think you're a bad person or a stupid one or anything of the sort. I hope you look into these things with a sober eye, and are not just swayed by an ideology you think is correct. Ideologies are never correct, though in a sense they are never wholly incorrect, either. It's okay to be wrong about something, it's okay to admit there's more nuance to the world than "good guys" and "bad guys", it's okay to learn. Cheers.
