In a recent article about the two Koreas exchanging balloons carrying pamphlets (from the South) and garbage (from the North), the Wall Street Journal, talking about the two nations' economies, says the North was, "until the Seventies", more economically prosperous than the South. This really surprised me. I'm in my mid-70s, and I always remember the South being an economic powerhouse and the North being a basket case. Can anybody with more knowledge about these things explain the WSJ's economic comparison comment?
