Mentally ill people and some extreme alcoholics for sure.
But the system is relatively good at picking up most people who are prepared to make a minimal effort to get off the street.
It used to be much better but at least the basics are still working.
And yeah, definitely: North Korean TV is just choosing to show mostly BAD things from the USA.
And the USA is doing the same thing in regards to North Korea. Only showing bad things. It's not all bad.
It's not so much propaganda, as being very selective about what you show in the news.
The news in the USA will report what that Michael Jackson's daughter ran away from home. But ignore that 1000s of kids in the Appalachians are poisoned and get cancer from the mining industry there. Or that 1000s of kids are losing their homes every day.
Before we judge North Korea's TV, we should question how partial we are....
