I work as a faculty member at the same university Dr. Duncan refers to.  I also started with a very low salary, but am now one of the highest; I negotiated poorly when I started, and I suspect she did too.  Mentoring for salary issues was nonexistent.  As well, her story is her story, not universal.  The university has long had a gender salary disparity fund to address typically lower salaries of female profs.  Not perfect, but thy are trying.

Dr. Duncan wishes to engage in outright state discrimination, which, in her mind, is okay because of what she alleges happened to her.  Typical Liberal identity politics, though with tragic consequences.  A travesty in my view.
