> If both parents work they're also easily spending roughly 30+ grand a year on daycare alone.

Depends on how old the kids are, because at least in most cases, daycare costs are for a very short period of time compared to the the overall life of the child. And the average in most states is wildly all over the place.

We absolutely should be focused on free childcare, or ideally ways that parents don't need childcare to begin with, but I don't think that has a lot to do with household income. Hell, at that point, why as well talk about transportation costs, as it's different in a single household vs a two parent two kid household, and different still depending on where you live.
