Maybe not. The Republic of Korea (South Korea) is perhaps the most advanced country on Earth. Which is amazing, as they were just emerging from third world status when I served there (1978-79 and 1981-82) and still used large charcoal briquets (Ondol) to heat and cook with. They are VERY HARD WORKERS so it’s no accident. If the Germans (another group of hard workers) can assimilate their communist sector, I’m sure the Koreans can too.
It took a generation to get rid of the “Wall of the Mind” in Germany.
