Giving birth and Medical Intervention?

I want to know what other mothers and mother-to-be opinions are on medical intervention when a woman goes into labor.

Example:

A woman is in labor lets say she's about 6 hours in and at 4cm. The hospital has decided that things are not progressing fast enough for them so they give her pitocin. After having the pitocin her contractions have become much more frequent and very painful so she has a epidural. Now she numb and 10cm and is having issues pushing because she can't feel her contractions so the intervene yet again using forceps, vacuum, or even jump into a c-section. At the end of all this we all say "Thank goodness the doctors were there to intervene and save the baby..blah blah blah."

My opinion is that is the hospital never injected the women with artificial hormones a lot of this could have been avoided. Women have been giving birth for hundred of years yet now it's become a gong show and it seems like you are not able to fulfil your idea of what birth should be like. What's your opinion?
