Educating children requires too much energy and effort, and parents at the bottom are unable to educate and do not understand.
Middle-class parents may know, but they are busy at work and tired every day. Enrolling in a cram school is education.
Wealthy families can hire professional parenting teachers at their own expense instead of educating themselves.
Educating children is never a simple matter, such as teaching them to eat. Originally, children can eat by themselves, but parents are afraid of trouble and children eat everywhere, so they would rather feed themselves and their children, even if they lose their autonomy.
Therefore, most parents are really afraid of trouble, so they are unwilling to educate their children, thinking that yelling is education.
