Very true, same with me.
I have eight children - not many have done more on the demographic front.
I am getting jealous :)
A country whose citizens don't reproduce is headed for the ash-heap of history. They can keep immigrants out - Japan comes to mind - but eventually, all they've got is an elderly population and a great opportunity for a hostile takeover.
One can have all the right philosophical principles, but the real test is in the delivery room and the classroom: Do the citizens have children, and do they bring them up with republican virtues and practical knowledge? If not - no matter what good reasons they posit for avoiding those activities - everyone had better learn to love felafel and frijoles.
