Query: Do Not Buy - $30 not well spent...

Not a recommended book.I have bought it following the recommendation of the author Daniel Quinn. However this book is a major disappointment.It's a complicated text, with not a single new idea. It just keeps stating the obvious that children are:1. Negatively affected by adult mistreatment.2. Grow up to be unhappy and child mistreating adults.3. The above is heavily tied to the culture and prevailing ideology.Tell us something new...
