So why waste your time. The author basically contends that if a person doesn't have an M.D following their name that their advice and services are pure rubish. How many hundreds of pages should it take to convey this thought?If the author and the other finger pointers would spend just a tenth of their energy seeking ways to amend the many current health care crisises effecting this nation and bring an ounce of trust back into the medical profession then the charlatans will simply dissapear into the night. The USA spends the absolute most per person on health care, yet is beat in terms of benefits received by 20 some odd nations, many spending considerably less. Why aren't the real problems being tackled?At least the author is genuine in his cause, misguided as it might be(unlike some of the knock-off authors like Kurt Butler who are simply out to make a buck off of controversy.) Much of this information is freely available on his website.
