In the failing Soviet Union there were lines of people waiting to buy bread that didn't exist. Nobody had the authority to create bread or its components.
Here in the U.S. a person could collect enough aluminum cans to buy a loaf of bread in probably a couple of hours and every supermarket has shelves loaded with bread.
I can't see how external sources or internal subversion can explain the lack of bread in the Soviet Union. The explanation is that individual responsibility and individual gain were outlawed. Without them, there is no bread.
