The cause of homelessness is lack of housing.

I emphasize teachers because they are largely left out of the debate. None of the bombastic reports that come from Washington and think tanks telling us what needs to be 'fixed' - I hate such a mechanistic word, as if our schools were automobile engines - ever asks the opinions of teachers.

Many of us regard ourselves as mildly liberal or centrist politically, voice fairly pleasant sentiments about our poor children, contribute money to send poor kids to summer camp, feel benevolent. We're not nazis; we're nice people. We read sophisticated books. We go to church. We go to synagogue. Meanwhile, we put other people's children into an economic and environmental death zone. We make it hard for them to get out. We strip the place bare of amenities. And we sit back and say to ourselves, "Well, I hope that they don't kill each other off. But if they do, it's not my fault.

In the book, I write about children in first grade who were taught to read by reading want ads. They learned to write by writing job applications. Imagine what would happen if anyone tried to do that to children in a predominantly white suburban school.

Instead of seeing these children for the blessings that they are, we are measuring them only by the standard of whether they will be future deficits or assets for our nation's competitive needs.

But what is now encompassed by the one word (“school”) are two very different kinds of institutions that, in function, finance and intention, serve entirely different roles. Both are needed for our nation’s governance. But children in one set of schools are educated to be governors; children in the other set of schools are trained for being governed. The former are given the imaginative range to mobilize ideas for economic growth; the latter are provided with the discipline to do the narrow tasks the first group will prescribe.

The future teachers I try to recruit are those show have refused to let themselves be neutered in this way, either in their private lives or in the lives that they intend to lead in school. When they begin to teach, they come into their classrooms with a sense of affirmation of the goodness and the fullness of existence, with a sense of satisfaction in discovering the unexpected in their students, and with a longing to surprise the world, their kids, even themselves, with their capacity to leave each place they've been ... a better and more joyful place than it was when they entered it.
