I think North Korea passed the point-of-no-return when, a couple years ago, it devalued the currency by 90% and forced its citizens to exchange their old money for the new at face value. I don't believe there's been such a blatant government theft from its citizens since the Holocaust.
The resentment, from a people who had only just begun to accumulate the most pitiable amounts of wealth only to see it expropriated, must be enormous.
