Please stop. You are really in this thread trying to keep the white man at the top. Are you white? If not, then those articles about men versus women wage gaps are not about YOU. White men out earn everyone and women women even out earn people like you.
Here is a whole thread with pretty color graphs and linked sources (with all types of variables controlled for) that show that even for the same jobs women are making less.

Not to dispute the entirety of what you are saying, but the famous 78% gap for White women is touted as fact.
The reality is that when controlled for careers, the gap becomes like 4-5%.
If there was a way to control for willingness to negotiate for a raise, as well as a comparison of education --> position --> time spent at company, the gap would likely drop to around 2-3%.
The overall lazy statistic for 78% is largely due to career choice, on the part of misogynist parents, preconceived notions of a girl's math and science ability, the deliberate control of the SAT to give male students an advantage, and comfort in a career that has a higher-rate of women.
Imagine if shyt like STNAs and even RNs were 51/49 in terms of sex?
There are so many external factors that make conclusions difficult.
