Now you're asking some more interesting questions.
In the most "gender equal" nation on earth, you would think that most positions have gender equality. If everyone is encouraged to do what they like or feel comfortable doing in a career they wanted, then you would have equal men and women, right?
Well, evidently, no. https://www.youtube.com/watch?v=cVaTc15plVs
Here's a good documentary on the subject. Norway was voted as being the most "gender equal" nation on earth. However. In norway, career decisions are far MORE traditional now than in 15 years or so.
In on particular company, they found only 10% of engineers and construction workers were women. Whereas men who are nurses at a hospital are equally as rare, if not more so.
For some reason, when men and women are encouraged to do what they feel like they want to or comfortable doing, there's a natural separation between the sexes that forms, and nobody seems to be able to answer why, no matter what kind of laws are passed to ensure equality of opportunity.
In nations with STRICT, rigid separation and social expectations of women, you see much more parity careers pursued by men and women - such as in saudi arabia, pakistan, etc.
It seems that, the more you try to rigidly enforce gender roles, the less likely you are to get them. And of course the more you try to have parity between the sexes and let the genders do what they respectively like, you get more people electing to follow their gender roles.
