Such philosophies are based on fairly simple notions.
Capitalism is based on abundance, and the concentration of wealth by individual in the furtherance of abundance, from which they divide the profits, and also divide the risk.
Socialism-Communism is based on the idea of shortage and deprivation, creating the need for rationing and restricting personal choice. It is easily overwhelmed when anything happens to be in abundance, because it becomes a de facto currency, so this philosophy strives to create dependence and shortage.
Earth is full of abundance of a vast number of things, so capitalism works reasonably well. Socialism-Communism would be at its best on the Moon, because there, nothing is in abundance.
