The term 'capitalism' is often used as a smear by the adherents of 'opposing' ideologies like socialism and communism so let's agree on a definition using Britannica Money's example [1]: capitalism, economic system, dominant in the Western world since the breakup of feudalism, in which most means of production are privately owned and production is guided and income distributed largely through the operation of markets..
Given this definition and weighing the positives and negatives it still seems to be the best system, something which I do not see changing as long as humans remain in control of society.
Do you have any examples which show where another system has been proven to be superior at a large scale? That - scale - is an important factor here since there is a direct relation between the scale of the group and the applicability of economic systems.
