S Kor has the expertise now to deal with the mineral and industrial wealth of the North. Korea united would do very well.
South Koreans have a very high level of expertise at many things. I don't see how they could successfully assimilate their N. Korean counterparts after so many generations of brainwashing.
"Korea united would do very well."
Not even the South Korean Government believes that. I doubt the Souths economy could stand the strain. It would be far worse than West Germany absorbing East Germany.
It would take a slow transition to make it work, and I don't think Kimmi will go for that.
