Some kids (parents, really) are beyond helping. They drag everyone in the classroom down and there's nothing a teacher can do about it. The kids are ruined because their parents ruined them. These kids need to be held back, separated, and/or expelled to give the rest of them a chance at a real education. This will require a change to incentives and laws, the first step of which is this growing awareness and dread of the situation.

This is one of the biggest issues. We allow children who do not want to and will not learn to destroy the education of those who do. We used to understand this and expel the disruptive students to allow the good students to actually learn.
