The gender pay gap is a myth. It's illegal to pay two people who do the same job differently (Equal Pay Act of 1963).
Do you know how they come up with the "77c for every $1 a man makes" line? They take every man working full time in the USA vs every woman working full time in the USA.
This obviously does not account for women leaving and re-entering the workforce for reasons such as family life, child birth etc. Then you have the industries women join, favouring nursing/social work and cleaning vs the highly male jobs such as being a doctor, engineer or I.T professional. There has been countless studies and articles dismissing the so called 'Gender pay gap' but it's still parroted by feminists and low-information voters even though the evidence does not stand up and when they're presented with that evidence they dismiss it as 'misogyny' and ten other buzzwords to silence you so they can continue the ridiculous charade.
“there’s a disparity not because female engineers are making less than male engineers at the same company with comparable experience. The disparity exists because a female social worker makes less than a male engineer.”
