ELI5: why does Kim Jong Un and the Kim dynasty keep their people secluded?

Are they trying to create their version of a utopian society? Or is it that they are just control freaks? 

Surely Kim and others realize he isn't a Dear Glorious Leader or some kind of God right?

Everyone (outside of NK) knows that there are huge problems in North Korea, such as people starving, poor access to electricity, and a lack of education. The only way to maintain that kind of status quo is to make sure that people don't know what the outside world has to offer. The Kim regime is able to live a very good life while most of the people in the country are poor because most of the people in that country don't know any better, and are told that the rest of the world is worse and is responsible for their problems. If enough people realized just how bad they had it there would be a bloody revolt.
