Now you're getting into what the cost of a child is. My point was that as
the tax burden increases, the tax incentives for having additional children
also increases.

I have no idea what the cost of a child is, but it's probably pretty high. I
also made the point that the marginal cost of each child increases with
volume (call it an economy of scale).
