Here's how this strikes me. Whenever lefties throw out the "women earn only x cents for every dollar a man earns" argument, many of us respond "but if that's true, why does anybody hire men? If women are that much lower cost labor they should be the only labor that's ever hired!" Lefties, lacking even the most rudimentary understanding of economics just roll their eyes and call you a hater.
BUT we have documentary evidence now that in one industry it is flat out true that women earn less than their male equivalents: hypocritical liberal Hollywood! When Sony was hacked it came out that leading ladies like Jennifer Lawrence make less on a film than even the much lower marquee value male supporting actors in some cases.
And now Hollywood wants to make films with only women. Coincidence? Hmmmm.
The simple debate answer is people often hire for irrational reasons, and then you’re in the weeds with rational market theory.
