Jobs also attacked America's education system, saying that it was hopelessly antiquated and crippled by union work rules. Until the teachers'unions were broken, there was almost no hope for education reform. Teachers should be treated as professionals, he said, not as industrial assembly- line workers. Principals should be able to hire and fire them based on how good they were. Schools should be staying open until at least 6 p.m. and be in session eleven months of the year. It was absurd, he added, that American classrooms were still based on teachers standing at a board and using textbooks. All books, learning materials, and assessments should be digital and interactive, tailored to each student and providing feedback in real time.
