Even North Korean people who are not necessarily happy with economic policies are still loyal to the state itself. It's a military-first state, so whether it does very well on the economic front or not, is not central to public support for it.
People tend to overlook the fact that North Korea's economy collapsed at about the same time as South Koreans lost faith in their own state. The late 1980s and early 1990s were a time when South Koreans were questioning the very legitimacy of their republic.
People who cannot distinguish between good and bad language, or who regard the distinction as unimportant, are unlikely to think carefully about anything else.
