I'm not quite clear on what you're asking. It seems odd to ask whether a nurse is for or against a lifesaving procedure.
I'm not in favor of *unnecessary* c-sections.
I've never met a doc who did a C/S because they would make more money. I've seen a lot of not-completely-necessary C/S due to fear of litigation.
The nurse's role is to prepare the patient for the surgery - insertion of a foley, making sure she has the appropriate IV tubing and meds on board, getting her prepped in the OR (betadine scrub, slapping on the bovey pad), making sure the woman is in the correct position on the table, making sure fetal heart tones are okay after spinal anesthesia, making sure the physicians have everything they need for the surgery, generally making sure everything is running smoothly in the OR, making sure a timeout is completed, charting times, doing instrument counts with the scrub tech, etc.
Your average hourly wage nurse is not going to make any more money in assisting at a c/section (and she did a fine job describing all the ways nurses do that) than assisting at a vaginal birth.
C/sections can be necessary and life saving. They can also be unnecessary and increase risk for both mother and baby. Whether I am for it or against it depends on which of these is the case. Once they get to postpartum, their reasoning is mostly a moot point and I just take care of them and try to meet their needs.
