Let's not group the school teachers with police and scientists. The cops and the researchers work hard, so we can't blame them. The teachers on the other hand, have proliferated with the support from their unions. They work for less than 10 hours a week, and carry almost four times the salary which an average council worker (who works for 60 h / week) receives. And what do they do? They just brainwash the students with their political messages. No one is going to disagree if I claim that the quality of teaching has gone down the drain for the last few decades or so.
