The subject deserved to be tackled with seriousness and depth, unfortunately the author is too superficial in content, little factual, few prospective or visions. Yet the author seems to be a real expert in the field, but this is not reflected in his writing. The content is redundant, laborious in a lyrical style to be pompous. The book could easily be writing in under 50 pages. This book should be sold in pharmacies, the radius soporific.
