Yeah no body is arguing against that particular point. I have to say OP was just pointing out that preference on it's own can contribute quite a bit to the "wage gap".
Yes, I get that. What I'm saying is that it's reductionist to just chalk it up to preference and call it a day. It's a complex issue.
They are less in opposition then people in these discussions make it up to be. The same people who tend to take you seriously tend to also be willing to pay. And jerk culture tend to prevent your career development, will affect your reputation in front of third parties, and affect both your confidence and ideas about what you can achieve, so eventually you end up with less salary. Bad culture usually implies a lot of nepotism and ass kissing with people taking any dirty advantages they can - and that implies any bias against you being much more mattering then in good culture.
One exception is when higher salary is because of "moral values and ethics" trade-offs. And I would be very careful before I would imply that men are more likely to do that trade-off.
Perhaps the women that responded would rather get paid less than work in a bro culture because they find it unbearable, not because they don't value being compensated well.
