What is the author's style in Savage Inequalities: Children in America's Schools by Jonathan Kozol?

As stated in his opening chapter, the author has a long history of working for progressive social issues in various fields, but his first love is teaching. One can tell from his description of the interviewees that he likes children and respects all sorts of people equally. (He even comes to admire a callous, selfish teen because she speaks her mind honestly instead of hiding behind political correctness.) Kozol seems to feel that if the general public would think of the students as children instead of dangerous "others" they might demand these kids be treated better.
