That teaching, done right, requires all of a teacher's emotional and intellectual resources; that we accord teachers neither the respect nor the pay they need to function well in their jobs; that few public school teachers come close to the ideal or leave the students with anything like what they need to get by--all this seems like a good argument for better pay scales and reform in the educational system that produces teachers.
Teachers should be paid better because their job is emotionally and intellectually demanding.
Teachers are well-respected and well-paid members of their communities.
