This topic is so huge, extremely subjective and controversial, to my mind it's like flipping a coin but arguing that after it lands, the heads or tails are already doomed to need changes.
I will tell you that while I was born and raised behind the "iron curtain" where abuse of power was the name of the game, now after having lived the other half of my life in the "civilized"world, I notice very disturbing and more depressing similarities, deep down, right at the core of society.
I do not believe humans are globally truly capable to think clear, unbiased, and really vet out their intrinsic weaknesses and viciousness in such ways as to prevent these from getting at the top of the society. We are not bees nor ants, from which there is so much to learn! Sadly, qualities that I can see every day to prevail aren't the ones meant to do with general well being. Even worse, the "geniuses" at the top aren't that smart either, but they enjoy even more that aspect of "je m'en fous", exactly because they can.
Unfortunately politicians and manipulators cling to terminology of the wording as if that really mattered, but one could say red is bad blue is good because I say so, or vice versa, in reality they don't care - to them it's just a means to an end, conquer naive voter's emotions.
Having a good fiscal system and a correct way to measure and pay work and products is indeed great, but that's not what capitalism is about, it's about speculation and control. Fears about communism in Western society are exactly about the misunderstood parts, and that "oh my god why should my taxes pay his health". In fact the biggest crimes against humanity were done in the name of it, and that's what the biggest fear of communism should be.
Yet there are aspects of each "system" that have great value overall. Sadly, as a whole they're both stupid idealistic failures, and because of that societies who persist in clinging to one or another are doomed to waste the lives of these generations, until they'll finally wake up, if ever.
