For the lucky North Korean refugees who make it to South Korea there are very real, very difficult challenges of adapting to a completely different way of life.  Differences in education and language — not to mention learning to negotiate a world of ATMs, job interviews, grocery stores with 1000s of choices, computers, the internet — are extremely overwhelming.  In addition, the new South Koreans often have guilt from leaving behind family members, suffer from Post Traumatic Stress Disorder, or struggle with other emotional and sometimes physical issues from their past.  Also, many owe money to the brokers who guided them.
