Cheaper is very much not true if you value time. Devoting the entire workday of an adult to 1-3 children is a huge cost, much more expensive than having one adult handle 6-10 children. And "higher quality" isn't guaranteed at all. Even with daycare the children are with their parents most of the time, and meeting up with other kids and a trained caregiver during weekdays has a lot of good effects.
