Unless little Kim Jong Kardashian dies beforehand and the next ruler is mentally stable / didn't constantly suck up to the previous leader's ways
it's not that, its that they won't give up communism. usually communism is a pretty stable economy, but not in north korea. usually in communism, you give some of your profit to the government, and they redistribute it; i'm pretty sure north korea doesn't do this considering their people are practically starving.
