To add on, my teacher friends told me that nowadays they also don't dare to scold students cos students will say they depressed, then go cut themselves or want to die, then become is teachers' de fault.Cause and effect
if you want to know the reason behind something today, look back over the years.
Population decrease - what happened a generation ago?
Disciplinary problems- I opine that since 20 years ago, teachers are not allowed to discipline students and with the western influence, even spanking by parents is not allowed as it’s child abused. Heck, even scolding children is frowned upon as psychological abuse
So we are where we are today.
