This 2012 study of Science faculty at research universities (full text available at the link), performed by professors at Yale and recently gaining media attention again shows that Science faculty, who are literally trained to be objective and impartial, still rate women as less competent than male candidates with identical application materials. References 15, 19, 20, 21, 23, 24, 25, 40 might be particularly interesting additional reading.

If existing as a woman requires that you be markedly better than your male peers to be considered equally good before you even walk through the door, let alone get an interview or attempt a salary negotiation, how can you keep pretending that the entire wage gap is a myth and down to women's different choices?

Are you counting "existing as a person that is recognizably a woman" as one of those poor life choices?
