The original pay gap came from a trash paper which compared average pay of women and men across disciplines. So you had doctors and engineers grouped with nurses and daycare workers. That was the origin of ".75¢ on the dollar". Within most industries there is no paygap that cannot be explained by lack of negotiation and shorter work hours, among other factors. We also take it as a given that average performance of men and women on any task is identical, and that's nonsense.

The paygap myth is pure propaganda.

Edit: imagine my surprise when even CBS is admitting as much!
