North Koreans can frequent black markets and still consider themselves good citizens, as was impossible in the communist East Bloc. So the situation now is more like Japan or Germany in 1944, say, than like East Germany in the 1980s. Widespread government corruption? Check. An entire population of economic criminals? Check. Constant griping about the state, the party, even some joking about the leader? Check. Even good Nazis had their Hitler jokes. A general readiness to fight for the state? Well, there's certainly more readiness in the North than in the South.
