Kaesong Industrial Park did not make S Korea a powerhouse, it wasn’t even established until 2002.
The operating profit in 2011 was about $56,000 according to Wiki
What I meant was the low labor rate on top of excellent engineering made S Korea powerhouse. S Korea engineering skills are next to NONE through out the world. Considering the ratio of America to S Korea population one would believe they all are genius in S Korea.
To be considered powerhouse one does not need to be biggest only the fastest growing and S Korea has that.
