That point continues to elude liberals. I brought that up to one of my lib sisters (who made considerably more money at her career than I did at mine). She told me men just like to be sexist even if they lose money. I told her that was an exceptionally stupid argument. Any business that overpaid workers for sexist reasons would find themselves out of business in a short while.
She didn't want to hear any rational arguments, she wanted to believe the lib canard about women being oppressed.
What about the women business owners?
Why don’t they hire all women for the 23% competitive advantage?
“ah... you’re oppressed... isn’t that cyooooot!”
