There are many supporting ideas such as success without modern education, criticism of American education systems, and the basic functions of modern teachings. Furthermore, the writer's subjective positions can help understand his idea to the reader who has the same subjective positions as a teacher in public school, a father who has sons and daughters, and an elderly person who wants to change the American public school system, which force the school and not real learning. These examples help find the reason why people change the school system. Gatto uses these controlling ideas to support his idea and to convince the reader by developing his questions about the shortcomings of the school system in the United States of America.
