I read in the WSJ that Germany is offering the equivalent of up to $30,000 to women to stay at home and raise their babies for the first year. They are offered and additional some if the spouse stays home for the next three months. It was causing quite a few women to try to delay delivery of their babies until after the New Year. Germany is hoping that it will inspire young families to have more than one child.
The problem in modern countries with fertility problems is the acceptance of immorality as normal. Paying people to have babies is going to cause more problems than it solves.
