I think the main problem is the medical guild exterminated midwifery in the early 20th century and "medicalized" women's normal pregnancy experiences. Doctors are doing better taking care of pregnant women in the modern era (more female doctors, etc), but I think they're still 'missing the forest for the trees'.
