Lime 5 (the book) talks about how MDs are forced to study abortion... and that no one really want to practice it as it's a lowly subject compared to Gastro, Neuro, Immuno and even Pediatric subjects....
It's a cash job... $350 - so, of course, it will draw some.
You're seriously uninformed if you think this woman is collecting $350 per abortion, or anything in that ballpark. She's probably barely covering her airfare and malpractice insurance.
As for medical students, since abortions are fairly often needed in preeclampsia cases to save the life of the mother (and the fetus would rarely survive anyway), it would be irresponsible not to teach the basic procedure to medical students. They also need to know how to abort ectopic pregnancies, which if not terminated, are also usually either lethal to both mother and fetus, or lethal to the fetus and leave the mother with impaired fertility.
My son has dated a young woman for the past two years. She just started her residency in OB/GYN. For a variety of factors, they broke up. I was relieved. It would have been hard to have a daughter in law who had performed abortions. Hell, maybe she already has.
