My wife is from Busan and her parents don't speak English nor are they educated, and I would consider them extremely "Korea Conservative", nevertheless, they're aware of the issue and it is discussed openly, how to continue to emerge Korea, and I think it is this issue that primarily made them comfortable with their daughter marrying a foreigner, of the options, marry a foreigner or destroy the country, I suspect Koreans will take the latter. If I had to guess, your countrymen will fair a lot better than expected, likely through policy of controlled "acceptable foreigners", strong demand of cultural adoption of said "acceptable foreigners", and through Automation/Robotics/AI. I was very surprised to see a lot of conversation among the young people in Korea about the future of the society surrounding the themes of what a hybrid socialist/capitalist robotics AI utopia would look like, if I was to bet on anyone getting there, it would be SK.
