It’s valuable to remember what economies look like without real prices and the free flow of information, services, and goods.
I know a retired military officer who once told me that as relations between the Soviet Union and the United States thawed in the late 80s the base at which this officer was stationed hosted a group of senior Soviet military commanders.
The Americans gave the Soviets a tour of the base and they examined the jets, hangers, and the rest. But the thing which absolutely amazed the generals was the commissary, where they saw not only officers shopping, but enlisted people too. They were astounded at the quality and variety of goods and accused the American staff of staging the store for their visit. The generals could not imagine that such bounty was readily available to so many. Our enlisted people right out of high school ate better than they did.
