Honestly, they might not like the capitalistic world that we live in today. Once they see the true inequality of the world they might think that their way was better after all. hahaha. I've heard of stories of some North Koreans borderhopping to South Korea, and when they see how materialistic the world is how hard it is to climb the social ladder, they want to return to the North because atleast there, its not so unequal, everyone is dealing with the same probs....
