If you want to turn the responsibility of raising your kids over to government employees, that's your call.Because you can't find time for your kids? Teachers are not supposed to be surrogate parents and it's a big mistake to assign them that responsibility. Many teachers are predators and most of them are idiots.Not another conspiracy theory.
It's not a "Conspiracy Theory" eg. the British Government has people spying on children, including to point of asking teachers to monitor children.
The other week, this referring to the EU Referendum, a teacher called the police, when she discovered a teenage boy looking at UKIPs website in the classroom.
Teachers have always been better equipped than most to notice if a kid is going off course. They spend more waking hours with our kids than we do. I want them to look out for their well being.
Kids are in school and interacting with the teachers for practically as many waking hours as they are with their parents. That is just fact. It makes sense that adults who have that much direct interaction with them should also pay attention to the clues that could indicate when a kid is going off course. If you want to isolate your kids from the real world, that's your call.
