There are many women who go into those fields; however, I think there’s still some societal attitudes (gender roles and all) that may discourage other women from exploring them. And women don’t really have a reproductive duty more than adults / parents in general have a family duty. It takes two, after all.
For your second part, you seem to contradict yourself - you say that women are bad at negotiating salaries and ultimately end up working for less than they deserve (which would mean they do deserve higher pay based on the work they do), but also that men get paid more simply because they work harder and better than women do (implying that women are being paid what they deserve). Which is it?
Lastly, i can’t help but notice that you cite traditional gender roles as support for traditional gender roles, in that the societal trend of keeping women at home (who would possibly be better off doing other things) causes women to work less, which you interpret as a sign that women naturally belong at home. In addition, I could create the hypothetical counterpoint of saying that if wives had *husbands* at home, then *they* could be the ones to work longer and harder at their jobs. Either one is just a reflection of whatever happens to be the gender employment ratio, not any underlying biological differences.

Which is it? It is both. There are many factors that exist simultaneously.

True. The question is, are those causes or effects.

and the biological differences between men and women *do* support traditional gender roles

it makes a lot more sense for the one who is 8 months pregnant to not have to go out and work

and I don't know what you mean by "are those causes or effects"

oh, you're pulling a "women would do all the high power jobs if society let them" meme

I would also not want a woman who is 8 months pregnant to have to go work

Do you support parental leave

You mean federally mandated parental leave? No.

Also, that’s not what I am trying to pull - I’m saying that women are somewhat more disproportionately excluded from high-level jobs than the sheer talent differential and work ethic provides for

Have you ever worked for a company and met your executives

would you want your employer to give your family parental leave?

like 75% of the c-suites I have met have been men over 6 feet tall

ouch

and the other 25% were men with foul tempers

it takes an imposing presence to control an organization

That’s 100% men

women cannot be imposing

it is very rare for a woman to be capable of leading effectively

I would disagree that it’s very rare

they are short and weak

they do not create respect

not in the leadership kind of way at least

Angela Merkel and Theresa May deserve at least some credit, I think

Although they are different types of jobs

Merkel is childless and is destroying her country

What’s your opinion on Thatcher

I don't care to have a strong opinion on most politicians

I see

some women throughout history have existed who can lead effectively

Yes

they are rare, but Joan of Arc and Queen Boudica in Britain come to mind

they are anomalies and they achieve their leadership role by acting like men

My opinion is that there are cultural biases that prevent women from achieving the same level success they could if it were absent (not that they are biologically the same at everything)

most cultural biases exist to reinforce biological biases

theya re not as flawed as you think

Yet there are flaws

they are minor, you liberals are throwing the baby out with the bathwater in this war on tradition

Society would be more successful as a whole if everyone were able to achieve their potential without being impeded by cultural biases

Well
