It is obvious that you have not observed a grammar grade lately. Children are raised completely different today than 45 years ago. Children cannot be left alone in a classroom for fear of a lawsuit if something happened and there was not an attending adult left with them in the room. Teachers do have to take a bathroom break and attend to sick students who have to go to the bathroom, which sometimes is 500 yards from the classroom. If the teachers had to take up snack, fund raiser, and lunch money; check and turn in attendence records, help each kindergartner pack up for the day, get their snack at snack time, plus hundreds of other things that are in their job description that does not pertain to teaching, there would not be much time left for teaching.
