An entire industry is profiting off of tactics used to punish mean children at school.
One consistent element is that “solutions” such as this one never explicitly regard bullying as a symptom. As such, when causes are discussed, they are couched in terms of character defects.
Inconceivably, the captive environment of school is rarely, if ever, taken into account by researchers or faculty when assessing the behavior of students.
The only way to constructively deal with bullying is to give students appropriate degrees of autonomy and not compel them to be in oppressive environments where they are subjected to people they despise and deprived of any control over their lives.
