I really wish people would stop obsessing over this. When all the variables are accounted for, the pay gap, if you can call it that, is somewhere in the 0 to 2% range. In some cases, it even reverses…which is exactly what you would expect to have happen if there was no gender pay gap.
Furthermore, the notion that girls are “kept out of STEM fields” is a clear misrepresentation of the facts. Nobody keeps them out. They keep themselves out. Blame parents if you want to. I have worked hard to get my three girls to embrace math. Two are step-daughters so I didn’t have the full 18 years to succeed. The third I’ve been working on for 15 years and so far she doesn’t shun math.
Too many youth today shy away from fields of study that are “hard”. We need to be raising a generation of youth, boys and girls, that have the grit to press on and overcome challenges, mental and physical, rather than just take an easier path.
