I've never met (virtually or really) onr single person who thought teachers were overpaid, who didn't make that calculation based on the students' seat time. EVER.

Every_Single_One of them would calculate the pay rate based on how long students are in class and assume that every day off for a student was one for a teacher and that the teacher wasn't working unless it was between the bells.

The gross misunderstanding about what teachers do is one of the bellwethers I often use to point out that our lip service to education is just that. It wouldn't be conceivable to have a culture wide error so grotesque if education were really a priority.
