DPRK's subway system is clean because the punishment for littering is so severe. if someone gets a ticket for littering in NYC people on HN are all up in arms. I don't have a link for it now but take a look at the comments for the story about the policing slowdown in New York when they stopped writing tickets for parking, turnstile jumping, and other minor offenses. People were all like "yeah, we don't need parking tickets! Society works fine without them, they are just for revenue! Punishment does nothing to effect behavior!"
