No no, it's "FUNNY girl"
Tax incentives for having children don't come close to making up the cost of raising children. Without the incentives the cost is merely higher. Poor people, whose children's care is paid for through public funding in some shape or fashion - health insurance, child care, food, and so on - typically do not pay taxes and therefore tax incentives do not benefit them. Anything that would result in a refund on taxes, would result in paying them.
I'm for education, but good luck getting the Catholics and the more stodgy protestants behind you.
