Ehh, there were a few insanes back then but at least they had 2 or more braincells
You gotta take into account that women usually do safer and easier jobs. Like, only abt 5-10% of women actually work on construction sites, firefighters, and the military.
Essentially, very few women are a part of "society's builders and defenders"
You can't just pay a woman that works at a McObese's the same income as a man who literally risks his life out on a battlefield
