North Korea has 100% literacy. I know this because I was looking at a set of photos (sorry no link; I can't find them again) which showed North Korean people doing humanly relatable things- like waiting at bus stops and learning to play the zither- with not a single overbearing image of the Dear Leader in sight) which came accompanied by little nuggets of statistical information- mostly upbeat- which were attributed to the CIA.
The CIA? Bloody hell!
So in the wake of the epochal handshake between Kim and Trump the Company is rowing back on the black propaganda and putting out pink propaganda with sparkles in it.
