Isolation Rooms In Schools

I have to confess that until a few hours ago I had no idea that schools had isolation units, something like solitary confinement for reluctant and uncooperative students.
Such cells did not exist in the schools of my youth. When the little Revoltettes were at primary school sometimes the more troublesome children were taken out of class and sat in the corridor, outside the school office. At their secondary school, which was private, there were no such isolation units.
So this is where compulsory government 'education' leads too - semi literate children and young people, pointlessly restrained in meaningless learning activities, herded together with their peers instead of working and dealing with the adult world, punished with isolation should they show spirit.
What is amazing though is that the pseudo Left will tell you that solitary confinement is not punishment. They are merely managing the children, conforming them to the system. The teachers have no authority, only power. Without authority there can be no values and without values here can be no worth, and nobody worthy of punishment.
And so all crime is permitted to those with Power in their quest for total conformity.
