In response to the negative review, it is ridiculous to talk about human progress built on the effort to compete when the negative results of this so-called progress are so evident, both in terms of the rampant unhappiness and low self-esteem of people in the "wealthy" world in spite of their success, as well as the horrific destruction of natural resources in the wake of such progress. The majority of people are in jobs that they detest, competing with one another for things they don't even want. Obviously, this outdated competitive model is questionable. It is also ridiculous to say that writing a book or expressing oneself is necessarily a competitive act. To put one's thoughts "out there" doesn't mean that you are concerned with how your book does in comparison to someone else's. I know that for myself, as an author, it is not a consideration. If it's helpful to people, and they buy it, then I make a living, which has nothing to do whatsoever with competition unless I make it so. If they don't, so be it. Mr. Kohn has proposed something very valuable to anyone who works with children - as an educator, parent or volunteer. It is quite obvious to see children shrink when competition is required. They need to know that who they are is even more important than what they do. That creates people who strive to compete with themselves and not others, which is never more than comparing apples and oranges anyway, as we are all unique and tests are inadequate to show that. I recommend this book to anyone who is a supervisor, manager, teacher or parent.
