I'm of the opinion that parents are largely to blame for all this stuff. School is viewed as daycare and education not really prioritized by a large part of our population. Teacher's get all the blame and that's not right at all.

I'm for things that entails negative consequences for the parents prior to the kid being pigeon holed as a deplorable or unfitting for academic environments. Sending them home is one way to make the parents suffer. But before that, let's group them together and then find ways to level them up as a cohort. Everyone suffers when the class has a huge standard deviation of skills/knowledge/enthusiasm/engagement/support/etc.
