Difference in salary has nothing to do with gender, as there are more women doctors today than men. The fact that there are differences (in responsibility, competence, and well, income too) between professions is normal.

When I said I have no stats, I meant that when you (I mean you, linca) claim there is discrimination, it's not me to bring arguments.
Or I notice your arguments have more to do with the lack of enough nurses, differences amongst professions and hierarchy, and other such things that are normal and have nothing to do with discrimination or the subservient status of the nurse.

French railway unions speak exactly the same way about train drivers and workers, while their condition has absolutely nothing to do anymore those 100 years ago - suffices to look at a tram driver's hypermodern cabin today, the effort it takes him to push some buttons  and, of course, the stress of largely doing nothing all day long.
