I would be very surprised if the average North Korean is really aware of his plight. Neil Boortz told a story of some Russians he befriended during the waning years of the Cold War, when he visited the nation in an exchange program. He and his wife accompanied the Russian wife buying groceries for a meal celebrating the couple's first night staying with them. Took most of the day - stand in line at the government bread shop, stand in line at the government green grocer, stand in line at the government butcher shop, etc. The Americans told the Russian lady about supermarkets and she just nodded. Years later the Berlin Wall fell and the Russians were able to leave then-Russia to visit the Boortz family. They repeated the ceremonial first meal by taking her to a supermarket. Two steps in, she stopped, shocked, and began to cry. When asked what was wrong, she told them she was simply overwhelmed by the sight of so much food from which to choose. The Americans were puzzled. After all, they had told her about supermarkets; she had even seen them on television. She simply believed it was propaganda; she assumed that everyone one lived more or less like people in the Soviet Union and like the USSR, simply created propaganda to make people believe their country and way of life were better.
This was a relativly well-to-do Russian couple in Moscow. They had a spare bedroom, a television set, an automobile, were politically trusted enough to host foreign journalists. Yet they could not believe that America (or Europe) was significantly better off than the USSR. Compare that to the average North Korean, who has no source of news other than government-provided and is under constant threat of death, torture or enslavement. Can she really conceive of a lifestyle as the average South Korean enjoys? I'm guessing that to the extent she even ever hears about such, she too relegates it to propaganda, if not some government scheme to test her loyalty.
