$875 is in Canadian dollars in a large urban city.

I stand by my comment that $4/hour childcare is good value. Please show me somewhere in North America where that is expensive.

No one is claiming that paying that is easy for everyone, merely that taking care of someone for 9 hours a day, including meals, for $40/day is actually ridiculously cheap. I can't think of many (any?) services I could pay for that would cost a mere $4/hr for labor+materials.

You'd actually be surprised that most at home daycare providers choose that profession. Most typically have their own child and decide to also take in a few other children to make extra money. I ran a startup in this field and worked with many dayhome providers. Some do it as their career, some do it for a few years while their children are young and they would like to stay home and be with them.
