None of this establishes that there aren't other reasons for wanting a high-paying job besides attractiveness (e.g., not wanting to be dependent on finding a spouse with a high-paying job).
Also, this would imply that gay (non-bi) or asexual men, who are not seeking women as partners, would be found in high-status/high-pay positions at rates more comparable to (all) women than to straight men. This seems like a pretty straightforward hypothesis - do we have the data to test it?
> All of them more credible than „theres a giant conspiracy against women“.
Why is that not credible?
Remember that until the 1860s, the United States literally had a giant conspiracy against black people - so much so that huge parts of the US economy were absolutely dependent on black people not having the rights to life, liberty, and property.
Women didn't have a constitutional right to vote in the US until 1920, when the Constitution was changed to add one.
Why is it not credible that there's a giant conspiracy against women? What changed in the last 100-150 years that made humankind more reasonable, given how completely unreasonable humankind was just a couple of generations ago?
(Note that I'm only speaking of the US, which is what I'm familiar with and where the US is based. It's possible that countries other than the US are more reasonable.)
I would be inclined to agree with you if the phenomenon was limited to the US. But its not, it occurs world wide, even in Scandinavian countries.
What you are suggesting is a world-wide conspiracy, across all countries and cultures, and across all corporations. I can't prove you wrong, but Occams Razor tells me this is unlikely.
