Teachers are put in an impossible position with students who come from homes where the parents don't do their proper jobs. It's never been easier to be a neglectful parent. Your child will be entertained non-stop by an iPad and a video game system. They won't get bored and bother you. You can send them to their room and do whatever you want if you don't care if they are sleeping or not, as long as they are quiet.
The "iPad babies" are an epidemic in schools.

My sister is a K-12 educator in a poor, rural public school system in southeastern Virginia.
In recent years, she's seen a surge in students who are sorted, improperly, into special education classes. These are students that exhibit symptoms of various learning disabilities, but these symptoms heavily overlap with the symptoms of children who are sleep deprived and over stimulated by dopamine activating content on the devices they are addicted to.
