If you haven't read Mark Steyn's America Alone yet, here is a large collection of money quotes from the book to give you an idea of its main points.
Steyn has been sounding the demographic death knell for Europe for some time now, but no one in Europe is listening. I hold out no hope for Europe. They will never wake up but will slowly sleepwalk into oblivion.
And the reason for the demographic decline? Some of it is industrialization, some of it birth control. But sexual immorality is also responsible, because people (read: men) who can get some by merely hooking up or shacking up have no motivation to put a real home together and raise children. It is better to sit in outdoor cafés, sipping fine wine, nibbling fine cheese, and talking about politics, undisturbed by nattering toddlers. It's the good life, you see.
In other news, by the year 2050, if current trends continue, 60% of Italians will have no aunts, uncles, or cousins, because everyone will have been an only child.
