I think the bigger question here is: we now have over 50% of people enrolling in medical fields being women. It stands to reason that this is because discrimination was taken away. Why didn't the same thing happen in math and engineering fields? Are we really supposed to believe that women entered the medical field in vast numbers because the medical field rapidly became much more welcoming of women? Do we really believe that women didn't enter engineering fields, as they have done in medical fields, because of widespread discrimination everywhere in North America?
