Men used to work close to home and their kids were with them. Dad would teach his children along the way, when he was lying down and when he rose up. It was not just mom while dad was off building a "career" and when he came home he was tired and the children should not bother him.
At some point in the 1800s it became acceptable for men to leave their families behind to do other things. Oh they would come back to bring presents and father another child or two and then they would be gone again. Not all men, but a good number. And as the decades rolled on men began to be gone more and more and their interaction with their children became less and less.
Finally men just left. And that was acceptable too as long as they gave money.
Fathers went from interacting with their children many times daily to wallets with legs.
