What this war has demonstrated is that private capitalism—that is, an economic system in which land, factories, mines and transport are owned privately and operated solely for profit—does not work. It cannot deliver the goods. This fact had been known to millions of people for years past, but nothing ever came of it, because there was no real urge from below to alter the system, and those at the top had trained themselves to be impenetrably stupid on just this point. Argument and propaganda got one nowhere. The lords of property simply sat on their bottoms and proclaimed that all was for the best. Hitler's conquest of Europe, however, was a physical debunking of capitalism. War, for all its evil, is at any rate an unanswerable test of strength, like a try-your-grip machine. Great strength returns the penny, and there is no way of faking the result.
