If one wants to boost the rate of "in-wedlock, Italian" childbirth, the problem there isn't that people lack money, but that they lack meaning. I suspect the only way to supply what's lacking in the "meaning" department --- addressing the faith, hope, and love gap --- is a revitalization of Catholicism, something the state can't do because it's a spiritual --- not a political -- thing: not the state's job.
Kinda creepy to my mind.
