Imagine the violence that would be wrought on helpless kids by parents already psychologically stresed to the breaking point by their jobs and life in general! Most parents see school as daycare anyway. Now remove that barrier of relief from kids who drive them nuts in the first place. It would be infanticide on a massive scale.
I would never advocate homeschooling for everyone. I'd simply prefer to see all education sold on the private market. So, schools would still be an option; no doubt, there would be an even greater variety of them. They just wouldn't be run by the state.
Of course, that wouldn't solve the problem of these monsters targeting any place where children are. And I understand the importance of self-protection. I just always wonder at the idea that schools are so necessary for children to learn, that even in a climate of rampant violence, we have to continue to send them there.
Eons ago, I went to the type of high school where the teachers were afraid of the students. A lot of the students were afraid of each other, too. Eventually, it did become like a prison. There were so many drugs passed around outside, that the whole school was banned from going outside at any time during the schoolday, even lunchtime. There were (unarmed) security guards there, and one used to participate in the drug activity with the students.
With all the fear and conflict, it was not the best learning environment. I can't even begin to imagine what it's like today in school. The violence seems to be escalating, and I wonder how much longer parents will put up with it all.
