2. The country has a caste system
The government uses a system known as “songbun” to determine the worthiness of its citizens. Unsurprisingly, the people constituting and closest to the government form the elite who receive the best opportunities in the country because they have the highest “songbun”, and these form the “core” class. The “wavering” represent the middle class or the average citizens, and the “hostile” are those who have ever made the mistake of irritating the government. These people are forbidden from living in Pyongyang, the capital, where the cream of North Koreans resides.
