As a counter to this point there have been scandals in England (eg Morcambe Bay, but there are others) where midwives killed babies through a combination of incompetence and arrogance, creating a dysfunctional culture that promoted midwifery to the exclusion of other professions - all because they had an unrealistic belief about "normal birth".

In England it seems the safest option is to have a mid-wife led birth with medical help available. Having a consultant obstetrician available appears to decrease rates of intervention, not increase them.
