From the comments:
“For 23 years, I had a subscription to the New Republic. The New Republic, not Commentary, not National Review.
For all of those 23 years, there were multiple articles a year on how demographic changes were coming that were going to radically change, if not doom, the social democratic societies. Author upon author stated the economically obvious: the numbers just simply could not be made to add up.
And now, the days of reckoning are upon us. There will be even more hard choices ahead.”
