I can tell you that your comparison is already flawed with you being restricted by what you saw in N. Korea but I appreciate that you are showing your experiences which is very important regardless and I appreciate so much for taking what footage you could and how amazing S Korea life is. Still, It's very important to remember there is a lot happening behind the curtains.
I recommend anyone to watch this video from Vice. It shows the eeriness and complete show for tourists. Here is an article from Newsweek showing a glimpse of what N Koreans that you don't get to see go through. That article would make a little more sense if you also knew that N Korean citizens have POOP QUOTAS. As in, they must have a certain amount of poop or go to their inhumane labor camps where they undergo many horrors.
Please check out the stories of escapees and other things that have gone on there, I just don't want people to get the wrong impression that this is how bad N Korea is because trust me, it will break the bar the more you dig in.
