I'm old enough to remember a time when both parents didn't work full time and the other parents in the neighborhood helped watch each others children from time to time. It didn't cost much money, and the part time wages were plenty to cover a lot of expenses. Unfortunately, the value of our money was destroyed by politicians, and wages have been depressed for several decades due to economic policies in place.
* Of course some other jobs were created in the process, like more caretaker jobs, and other stuff happened like more automation.
