I agree.
My Korean isn’t good enough to know whether there is any debate in SK about the causes behind the pervasiveness of bullying. It is always relevant to ask such questions.
In the West, for instance, the ongoing investigations into the bullying of women and the LGBTIQ folk in the militaries have demonstrated the deeply embedded cultural forces which have normalised bullying, have shielded abusers from accountability for generations and have created an environment of impunity. It is difficult to uproot bullying unless systemic measures are consistently implemented to achieve cultural and legal changes for the better.

I wonder if questions are being asked in SK about whether deeply enshrined hierarchical norms which are even reflected in the language have a lot to answer for in this regard. The idea that the powerful and the wealthy deserve veneration because of their status is not unique to SK. It has been a global scourge for eons and continues to be. The chaebols certainly bullied their way into obscene wealth relying on connections and expediency and that is only one dimension of how bullying has become embedded.
The acting and KPop fields tell their own horrifying stories. That so much ugliness occurs behind the scenes is shocking and terrifying. The hierarchical nature of any society assists the bullies and abusers in a multitude of ways. It isn’t easy to uproot abuse because really difficult questions need to be asked about why bullying flourished in the first place and continues. Humans don’t find it easy to look inward. In any country.

I love clever ways to outsmart bad people but I just can't stand bullying.

You should pitch this idea as a drama in itself! Evil people killing off the good ones before they are born to ensure they succeed in their plan to rule the world. Then setting up special nursery’s so they can corrupt the mind before the age of 7 so they can be fast tracked into doing the evil deeds from a young age. The alternative underground movement would be the good people who have to find a way to stop the evil plan from destroying humanity.
