One problem I see with this is your example of nurses. Women went into nursing in the past frequently because it was open to them, and being a doctor wasn't. That's changed, and now the only reason to be a nurse is because the educational requirements are much lower, and consequently, there's a shortage of nurses because who wants to do that instead of being a doctor and making more money, unless they don't want to spend as long in school and rack up as much debt?

Also, nurses are some of the least empathetic people around. Don't be fooled by the common misconception; they're usually not caring people at all. "Nurse Ratchet" is not that far from the truth. My mom was a nurse, and I've met many others; they're just not the nicest people around. And there's a good reason for this: a highly empathetic person would not last very long as a nurse. They'd get burned out very quickly, after seeing so many sick and dying people up close day after day.
