I still remember the shock of entering first grade, how structured everything was, how the teacher used a false high-pitched voice with exaggerated expressions to sound friendlier, how everyone thought that was normal and how she used that rapport to teach us to stand in lines for everything, agree with the group. When we were asked to work on the simplest math problems in a group, it was hard to reason with anyone because they would always go with the majority opinion instead of listening to arguments. I did end up getting a lot of respect when the teacher validated me.
We definitely infantilize our children in schools, teach them to act stupidly in order to get them to behave. Then we wonder why we have problems like youth gang violence.
