From the Weekly Standard:
Last week, the New York Times ran a piece on the dire demographic problems facing Germany. The short version: Germans aren’t having enough kids, and as a result the economy is in trouble and there are all sorts of logistical problems—vacant buildings that need to be razed; houses that will never be sold, sewer systems which may not function properly because they’re too empty.
***
Twenty-three percent of German men—that’s not a typo, 23 percent—said that “zero” was the ideal family size. There probably aren’t public policy solutions to a cultural worldview like that.

Note that in The Third enough people didn't want children that there was a robust child credit trading system for those who wanted more than two kids. If such a policy were enacted in Germany, I can't help but wonder how robust such a system would be would be.
