During the 90's I was a technology manager at Citigroup and Chase. In my time there I hired many folks and about 40% were women. Before anyone screams "discrimination", in the 90's there were fewer women in tech, I would estimate that roughly 25% of the applicant pools were women. Additionally the technology I was working with at the time was from the late 80's, when even fewer women were in tech. Things might not be perfect now, but there have been changes.. anyway, I'm writing about pay inequality. I'm going to tell you why most of the women who worked for me got paid less then men.
