I absolutely hate making this comment but I’m obliged to because I feel some you all are pointing at irrelevant factors, because you don’t know any better. Look at the birth rate for a better signal and the decline of single income families. Lastly, straight men, I’ll give you a secret women choose to go to school because we are taught at a young age that if getting an education is the #1 way to not be dependent on anyone. A man can easily walk out on you so it’s a poor decision to not get or finish an education. Look at when the data starts going up- that’s the generation that saw the last wave of traditional stay at home house wives and single income families. Unless you absolutely are called to be a house wife/trad wife at 18 with your high school sweetheart… you go to school. It’s pretty obvious.
