One can have a lot of respect for teachers and still like education reform.
That said, I've also worked with big companies. This does not obligate me to believe that big companies are universally properly managed collections of competent, self-effacing employees who would never dream of advancing their own interests at the stake of the job. It also does not obligate me to believe that big companies cannot be improved, even radically improved, by measures which would discomfit at least some people who work for big companies.
Indeed, if I hypothetically believed either of those two things prior to working for a big company, working for them would have cured me of those delusions, rapidly.
