This feels like the wrong goal. Why does it matter how much an economy can grow? Is that worth not having a parent raise the child? In my opinion, it’s important for kids to spend more time with their families not less. Having one parent at home is very useful for bonding, development, etc. And frankly no childcare, even one with good ratios of workers to children, can substitute for it. I think the notion that “if the children are taken care of” is perhaps not recognizing that there are different levels of “taken care of”.
Our kids are fine.
Turns out kids need a lot of time with other kids.
