I am also on my phone, so you'll have to excuse the poor cropping. It's the same chart as the one in the linked article. There are many studies that come up with pretty much the same conclusion - there is a measurable difference between median wages of men and women, which I also agree is true, but most (if not all, since, we're getting close to margin of error here) of it is accounted for by factors that women are in control of rather than prejudice or discrimination. I could probably find more if it really interests you that much, but from what I've read on the subject, when proper controls are in place there's no noteworthy difference between wages of men and women.
I always love more sources and more reading, so please and thank you in advance!
That being said, we can actually take this a step further and expand on how much of wealth is owned by women, and how that impacts education and employment. Much like minority groups, the impacts of discrimination and property rights regarding women in the past stretch on into today very obviously, and without a level playing field, it is difficult to improve upon.
