And I can assure you, there are interventions a institution can take that change situations for the better. IF the institution has the capacity to do so. I can only speak for European schools tho.
Speaking for central EU schools, there is no such capacity and the teachers sometimes join in the bullying too, and pretty often they ignore it when it's the popular children doing it.
It's also very hard to deal with it if you have 30-35 children per class and 3-5 classes per year - which you do because we are at the height of a population wave in this region right now.
They are also absolutely unable to deal with stuff like dyslexia, ADHD, or other mental issues - meanwhile we have a push for "inclusive schooling"...
Pease name these interventions. How big is the share of European schools that have the capacity to follow these best practices? In Germany for example, there is a teacher shortage.
