[how does a degree in math not help in the education of children? a degree in english? a degree in history? chemistry? science? biology? physics? etc,etc....
There's nothing preventing a married woman who really wants to from taking courses and studying math, history, chemistry, etc.
If that was the real reason young women went to college, to help to educate their children, they would do it whether they were married or with children or not.
But married women with children would quickly realize the folly of spending time and money on such pursuits. The idea that a girl would go to college to study math to later teach her homeschooled children math is absurd.
That's not why they go. The motivations have to do with pride, and far worse.
