Shouldn't we just call it a Monarchy then? The "communism" in DPRK is just some red paint applied on top of a religious monarchy, in which the Kim family is blessed by the gods to be the leaders of the people. This is as far from the ideal of communism as you can get. Or is the battle for preserving the original meaning of the word as the ideal of the workers collectively owning the means of production and directly profiting from them, rather than making one person on top exhuberantly rich, now completely lost?
Just in case you didn't read my previous post backwards, I'll take a stab at it. /wiki/List_of_countries_by_Social_Progress_Index lists countries by "social progress", which they define as basic human needs, foundations of well-being (whatever that means), and opportunity. (I didn't cherry-pick the source; this is the first one I found that included North Korea.) The data are from 2015. On this ranking, Denmark is 8th, with a score of 86.63, the US is 16th (82.85), South Korea is 29th (77.7), and North Korea is 134th and last, with a score of 20. (Something like 60 countries didn't supply enough data to be ranked at all.) North Korea is 11.42 points behind second-to-worst (Central African Republic). So by this measure, (Denmark - US) = 3.78, and (South Korea - North Korea) = 57.7. So, yeah, I'd say that my statement that " the difference between Denmark and the US is massively less than the difference between South and North Korea" is quite accurate.
You could also look at the Satisfaction with Life Index (https://en.wikipedia.org/wiki/Satisfaction_with_Life_Index), except that it doesn't seem to list North Korea at all...
Sorry for making you pull that data, but thanks for responding with data.
Second, the difference between Denmark and the US is massively less than the difference between South and North Korea, so that comparison doesn't prove your point as well as you think.
