It's worth pointing out that East Germany was one of the most (maybe the most) prosperous countries in the Soviet sphere, whereas North Korea is horrendously poor. To put some numbers on it, the East German GDP in 1989 was about $160 billion, with a population of about 16 million, so about $10,000 per capita. North Korea's GDP is about $12 billion with a population of about 25 million, for a per-capita GDP of about $600.
