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?"

There's definitely a tension between the way teaching is talked about and understood at the political level and how everyday average Americans think about teachers.

There are a lot of polls that show that actually Americans have a pretty high opinion of teachers, that Americans think teachers are just about as prestigious as doctors. And yet there's this political conversation - this reform conversation - that paints a very negative picture of the effectiveness of the teaching population. So there's definitely a tension between the way teaching is talked about and understood at the political level and how everyday average Americans think about teachers.

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.

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.

Younger teachers are definitely more likely to have worked at charter schools as opposed to have just heard of them. Charter schools explicitly look, often, to hire younger people. I've even talked to people who didn't necessarily go into teaching thinking they wanted to work at a charter school or even may have been considered critics of the charter school movement, and found that it was the only way for them to get their foot in the door. So young people just have much more familiarity with the concept.

When you see that 76 percent of teachers are female, I think you have to acknowledge that there's a cultural bias, and it does date back to this nineteenth century idea that teaching is a form of mothering.
