Another article about North Korea: "Born and raised in a North Korean gulag"
mentioning arranged marriages in North Korean prisons.
One who managed to escape says that he sometimes finds life "more burdensome than the hardest labor in the prison camp, where I only had to do what I was told." I think there is a similar phenomenon with people in the UBF camp. They are claiming that people who want to leave UBF are seeking an "easygoing life", but in reality, the life in UBF is much easier since, despite all the boring meetings, training, abuse etc., you "only need to do what you are told" which is in a way the most easygoing life style you can imagine.
