This is the second part of two posts examining how North Korea fell behind South Korea.
As the previous post found, for several decades North Korea kept up with South Korea. Then, during the mid-1970s, the country started falling behind. Ever since then the gap between the two countries has widened.
This post will explore several factors behind what caused North Korea to fall behind. There seem to be three main causes: the failed ideology of juche (self-reliance), the end of Soviet aid, and Kim Jong-Il’s incompetent rule.
