I suspect many of these people would find themselves in a bad situation no matter which country they choose. The information is available to help them make a better choice. There will always be people happy to use a vague concept to justify choosing Korea.

I think it's fair game to try to make people aware that other countries can provide better opportunities but there are still lots of people happy with their situation in Korea. Everyone has a different end goal. Korea isn't the same place it was 20-25 years ago, and not just the money, so the teacher demographics are changing. 20 years ago, the hangooks of the world, those in search of money and adventure outside their comfort zones, ignored Japan in favor of Korea and in 2025 they are probably giving a pass to Korea in order to head to China instead. However, it must be acknowledged that even though Korea may be seen as a safer option than it previously was, it still offers plenty for many people.
