This is something that Randi Weingarten said to me when I interviewed her once, which I think I quote in chapter nine. She talks about how only 7 percent of private sector workers in the American economy are in unions. So all the protections that teachers have that are due to collective bargaining - including generous pensions, generous health plans, limits to what they can be asked to do after school and in the summers - all of those things are sources of resentment to the public. And I think that politicians have played off of that quite effectively.

Definitely we see throughout history that American teachers are asked to be very self-abnegating. They're not supposed to be concerned with the conditions of their labor, they're not supposed to care about pay. This is the kind of vision of the ideal teacher, which is again and again brought to the fore by reformers, the ideal teacher as someone who is passionately driven to serve children. Almost to the exclusion of a more pragmatic view of what the job actually entails.

[Nineteenth century American educator] Catharine Beecher is really associated with the idea that a mother works with children in the home and a teacher works with children at school, and that therefore women are almost biologically predisposed to do this job.

I don't think school reform should be motivated by missionary zeal. I think it should be motivated by evidence of what works. I have been critical of Teach For America in the past but I think one of the things about their model that's interesting is that they're constantly looking at it and whether what they're doing works and reassessing their model, and making changes. So to the extent that I believe everyone in the education sector should be looking at evidence, reassessing, making tweaks to figure out what works, I think it's a positive model.

Just in general, when we look at our school system, there is so much overlap with our criminal justice system in terms of our low-income youth.

The question is rarely asked, "Why is it that so few other Americans have these protections?" The question is more often asked, "Why do teachers have it so easy?"

I think any sort of system that gives teachers more opportunities like teacher-led schools is a positive one that's going to lead to better retention in the profession, and it's going to be more intellectually challenging, so teachers stay engaged with their work over the many years of their career.
