Can Koreans immigrate to other countries to live?

For example, escape to South Korea, and then the South Korean government will give you a house, money and so on for free, so that you can become a full Korean citizen on condition that you help publicize how dark North Korea is. You can also flee to the United States and apply for a green card, which means political refugees, human rights and other excuses to discredit North Korea's entry into the United States.
