Sometimes someone will bring up the wage gap, that women on average make only 75% of what men make. Then some crusaders of truth charge in to inform them that in fact if you hold all factors constant, then you end up with something closer to 96%.
Do some people think that, when holding everything else equal, the pay gap between men and women is 75%? Sure, but to focus on them is to miss the important point people who are aware of both numbers but still stress the first are making.
Part of the problem is that men’s work is valued more highly than women’s work. For which the solution is not for women to all abandon whatever it is they were doing and become engineers, but for our society to better compensate about caring positions. That jobs with more men doing them make more than jobs with more women doing them is itself a problem. The problem can exist at two levels. The first is possible discrimination in getting certain jobs. There’s currently plenty of work being done to bring women into STEM-related fields. There’s also known hesitation in the corporate world to promote women, usually out of a fear of future pregnancy/child-raising. The second is, as mentioned, the jobs themselves having a bad compensation structure. Some jobs are woefully underpaid.
