I would rephrase the OP's argument to "capitalism is the best humanity has offered so far". Or to paraphrase Churchill "capitalism is the worst form of economy except for all those forms that have been tried from time to time". Note: I only mean real-world, tried-and-true forms of economies. Not in books, not utopias, only real societies. Because not even this capitalism is "by the book", many countries and many epochs defined it differently, with unions, with subsidies, with with with... there's a lot to be improved, but I still argue we didn't have better (or less bad, if you want).
