And that approximately 5% difference can be solely attributed to the fact that men are more likely to negotiate for their salaries than women. I don't remember the study off the top of my head but there was a YouTube video that was investigating the pay gap and referenced the study looking at men's and women's willingness to ask for more pay.
That might be part, but there are even simpler explanations. Taller people make significantly more money per inch. Why that is, who knows, but just by itself it can explain around half the wage gap - before correction. In other words, after correction, if you also correct for height, then women make more than men.
Of course no one should make more money just because they are taller, but that's the reality. No one seems interested to try to correct this, though, because it's not obviously tied to any popular political movements.
