What will happen when Korea is reunited? It's a popular question, with a great deal of ink spilled on the subject. Former President Park Geun-hye famously commented, for example, that unification would be a "bonanza" - partially an attempt to combat the general apathy many South Koreans feel towards the issue.

And why wouldn't they? With the two Koreas being radically unequal by also every standard: from GDP per capita to standards of living and quality of education, it's estimated that unification, when it comes, will cost South Korean taxpayers billions of dollars. Bringing the North up to the economic level of its Southern counterpart will not be easy.
