May I comment? We have lost the family allowance in Canada and lost the child dependant deduction and kept the spousal allowance quite low, so most people who stay home to take care of a child discover quite quickly that it costs more than they thought it would. The estimate is usually around $180,000 to raise a child to age 18.
We found that people start taking from their own savings, so it stops being unpaid labour and starts being reverse-paid labour: we are paying for the privilege of going unpaid. Of course we cannot save, and the household debt is a direct result of reducing all the social benefits for the care role.
