Well then be sure to check out Consumer Reports. That's right - even Consumer Reports thinks there is too much medical intervention in birth and has published their report entitled " Back To Basics For Safer Childbirth"
In it they conclude that, "too many doctors and hospitals are overusing high-tech procedures". It breaks it's report into two sections, Overuse of High-Tech Measures and Underuse of High-Touch, Noninvasive Measures. Of the high-touch (I like that!) measures, doulas ("continuous presence of a companion") and VBAC are on the list.
