Beyond that, what are their plans for the future? How does its government function and what is the general opinion that the DPRK's people have of their country?
Most importantly, where can I read about this sort of thing myself?
Sorry for giving incorrect information, the pricing info I gave was based on images from 2013. In 2014 there was a massive wage reform which increased wages by an insane amount and also rose prices by a lot. As of recently, according to Young Pioneer Tours in a mall food court in Pyongyang you get hotdogs for 5,000KPW, dumplings for 1,000KPW, roasted duck for 8,000KPW, Japanese pancake for 12,000KPW, and a plate of Mandu (dumplings) for 4,000KPW. These are more speciality items, but the point is that eating out is pretty expensive and DPRK citizens can't eat out 40 times a month.
About wages, 80,000 is an average but there is a decent differential in wages depending on the sector. Industries like textile give wages of about 15,000KPW/month, a cosmetics factory in Sinuiju gives around 80,000-110,000KPW/month, and more demanding professions like heavy industry and coal mining gives 300,000KPW/month.
