I taught North Koreans in South Korea. AMA!
My short bio: Seeing the AMA from a tourist who visited North Korea (something that you absolutely should not do if you want to help the people of North Korea), I thought I'd do this again. I've done a couple of AMAs a long while ago. About me:
I'm in my mid-thirties with a Ph.d. in English literature.
I was a tenure-track professor of literature at a South Korean university until leaving the country in 2012.
During my time in South Korea, I tutored some North Koreans and befriended a couple defectors who told me a lot about life in North Korea, in the military, and so on. I admit my information is dated (I haven't spoken to any North Koreans since 2012), but I'm happy to answer any questions if there's interest.
If you want to help the people of North Korea, please consider donating to one of the many groups out there whose mission is to provide assistance to those trying to leave the country. The nonprofit group PSCORE is, in my opinion, the best group that is actually helping people to get out of North Korea while also helping those people within North Korea try to change their country.
