Remember this next time a person says "but labour camps, tho".
So even if you take the highest estimate from the US State Department, the DPRK has 120k prisoners with a population of 26 million. The US prison population is 1.8 million* out of a total of 332 million. My calculator says that's 0.46% vs 0.53%
*This doesn't include the 3 million or so under parole or house arrest.
ah, but you see, the dprk has over a million people in underground gulags dug out by communist molemen. bet you feel silly now, huh?
Basically the dprk is actually a giant prison so it has a 100% incarceration rate checkmate tankies
