>Anyone tried to move away from this model where there is two people of opposite gender, living together as a family, working, and raising child(ren) at the same time? Why not have dedicated facilities that handle raising children professionally?

People in general have a built-in biological incentive to treat their own biological children well. People child-rearing just as a job generally treat children worse than biological parents, and the empirical evidence supports this (e.g. the earlier children enter paid childcare, the worse their outcomes on average). Only a small minority of extremely moral people treat other people's kids as well as their own biological children.
