content: Are you a believer of the 77 cents value? My understanding is that it was a value plucked out of the air and latched onto forever since the 1970s. If this value has any merit, then it has to be understood that it compares the pay of a CEO with the pay of a janitor. Engineers vs Teachers, and Accountants vs Nurses. What I'm saying here is that men tend to stay in Engineering and Accounting type jobs for longer than women, who can often drop out of professional work for families or because the lack of social interaction in the role. Teachers and Nurses are very important but they tend to have lower paid roles when compared to Engineers the like.
