It is a commonplace by now to say that the urban school systems of America contain a higher percentage of Negro children each year.

I wrote the first book, and I thought people would say: 'Separate and unequal schools in the City of Boston? I didn't know that. Let's go out and fix it.'

The contrasts between what is spent today to educate a child in the poorest New York City neighborhoods, where teacher salaries are often even lower than the city averages, and spending levels in the wealthiest suburban areas are daunting challenges to any hope New Yorkers might retain that even semblances of fairness still prevail.

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.

More money is put into prisons than into schools. That, in itself, is the description of a nation bent on suicide. I mean, what is more precious to us than our own children? We are going to build a lot more prisons if we do not deal with the schools and their inequalities.

I'd love to go back and teach primary school. I used to teach fourth grade and fifth grade. I'd love to spend several years teaching kindergarten or maybe third grade.

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.
