Based on 13 years living in South Korea (and a Korean wife!!!) I could quibble with a few of KublaiKhancun details, however in the main his points are valid. The fact is every culture has differences. Those differences will impact society in different ways. There is no right or wrong. I do feel that some aspects of Korean culture can impact things like flight safety. Those same aspects may very well however have a positive impact on society in other ways.
Overall there is no good / bad or right / wrong, just differences. In terms of air safety alone I do think there are valid concerns about the impact of culture on safety.
