Daycare isn't an appropriate analogue to your example though. A shift in culture that allows you to bring your children to work would be and would be absolutely sensible for white collar and several blue collar jobs.
Young children (under three) babble and screech and cry and explore and try to finger everything and put everything in their mouth and then screech when you take the thing away from them or try to restrain them from getting at that shiny object they really want. They play for a few minutes then come running over demanding attention and screech if you ignore them. They get hungry and cry, they fall and cry. And this cannot be trained out of them because they are too young for that.
None of this is a problem if you have baby proofed your house and they can wander and play with whatever they want, and if you are just doing chores and can give them the love and attention when they demand it and go back to your chore when they go back to playing again. But it is a big problem if you and other people are trying to concentrate and work.
I'd imagine many families are like mine, where our house is strategically designed for optimal childcare.
I have worked at places that paid for convenient nearby parking.
I worked at a university that had a daycare just across the street. Given the dramatic pay gap between there and elsewhere it must have been sticky enough for some.
