I don’t know how it works in the US but isn’t it normal that child care cost are higher than rent or mortgage? Unless you count as child care older kids (like above 3), you can’t expect a single worker to take care of more than 3 babies, and rent should be around 1/3 of income. So typical cost of daycare for 1 kif should be about typical cost of housing for 1 worker, no? For reference here in France, my mortgage is about 1300€/month and daycare (full time, private) for one child is 1400€/month, (of which about 700€ is paid by the state).
Indeed, this is why child care is or should be heavily subsidized.
