Thanks to. Humanity has attempted 37 separate experiments with communism in the last century alone, and they resulted in 100M+ deaths. To be clear, no one is claiming that capitalism is perfect. Merely that it is the best of all the options on the table. The problem with communism is that it doesn't account for the human element. Most notably greed, corruption, and nepotism. The reason capitalism succeeds where communism fails is that it embraces the ugly underside of humanity and harnesses it for good. Elon Musk would never have revolutionised internet payments, EVs, space-based internet distribution, and reduced space transport costs by 90% if there were no reward for him. Humanity benefits thanks to his greed.
