Although ducking the implications, this author is dead right on one point: it's the white, educated Americans who are having too few kids (people like childless me). He's unashamedly dark on his prognosis for senescent Europe — which by 2100 he expects to have been subsumed by Islamist fanatics from the Middle East. Yet he bends over backwards to bemoan the fact that Hispanic immigrants to the US gradually mirror lower native-born fertility rates over time. Oh, no, the Hispanics were going to save us from extinction! But the only faction in America facing "demographic disaster" is the dominant elite of European ancestry. Might this book have a subtext? In urging all "Americans" to have more children, the author seems secretly sanguine that the majority of his readership is apt to be white.
