No, unless you are North Korean citizens for years, it is hard to grasp the truth.
Of course, we all made this judgement, by comparing our life, and putting ourself in what NK's seem like living in right now, and adjudged that we would hate such a life, so the actual North Koreans must be hating their life as well.
But truth be told, Many of the people there haven't even seen foreigners in their whole life, they are like a modern tribe, living in seclusion, we have to let their curiosity take its course, instead of pointing fingers at them saying, "look how boring is there football" "look at that, they don't have any fast food chains " etc etc.
