The following is a quote on propaganda for production.

The North Korean government did not publish economic statistics, and if at all was not a reliable figure, it was distressingly trying to deceive not only visitors but also themselves.
It is common practice to produce statistics on agricultural production and industrial output so much that the manager is afraid to tell the boss of the fact. Since the lie snowman was swollen to the top of the organization, it is hard to imagine that Kim Il Sung did not notice the economic collapse. (Barbara Demick, Nothing to Envy:Ordinary Lives in North Korea)
No matter what kind of field, geology or agriculture, Kim cannot give advice. “Goat breeding and dairy production have been greatly improved thanks to Kim Jong Il’s on-site guidance and warm affection,” said Kim Jong Il after visiting a goat ranch near Kiyotsu. Korea Central News Agency said. (Ibid.)
