Here is a fact: every country in the developed world possesses an economy that combines capitalist and socialist forms of organization. It seems to me that this fact is something that used to be more widely understood and accepted. The economies of the mid-to-late 20th century emerged from long processes of contentious struggle between classical liberal, socialist and traditionalist ideas, and had all arrived at different combinations of those various elements. We used to call these economies “mixed economies”, and almost all educated people understood that we all lived in such economies. We debated which ones were better than others: which produced more prosperity, or more happiness, or more justice.
People disagreed, frequently intensely, but often understood at the same time that these disagreements were mostly practical disagreements about getting the right mix, and that the pure textbook forms of capitalism, socialism, communism, or whatnotism were abstract, purifying ideals that each left out various important aspects of human nature, and were thus too high for humanity.
Most people who pushed in a socialist direction understood that you can’t plan everything all the way down to the smallest pizza shop, and that you shouldn’t eliminate all of the confidence, personal pride and creativity that come from accepting some measure of individual control over private property. Most people who pushed in a capitalist direction didn’t really want private firms running all the law courts, militaries, schools, parks and highways, and recognized that a civilized and harmonious human society shouldn’t be based on the bestial norms of wilderness competition, with its cruel, Sisyphean struggles for dominance and survival. And most traditionalists understood that the kingdom of heaven is not of this earth.
