Women don't advance in rank as fast as men, and so end up being paid less. Thus article doesn't refute that because it admits that level is factor in the pay gap. As to why women don't advance as fast ... my opinion is that it's primarily motherhood that does it. It puts a career on hold for 6 months times the number of children, and women are socially expected to be primary caregivers so they feel pressured not to work long hours (and so advance less). Before they get pregnant employers will suspect impending motherhood and offer fewer opportunities so as to rely less. It's not fair, but it is how it is.
