This feels like a huge problem. You hear about inverted population pyramids and what it costs to have a small young working population support the larger old population. But there's a big difference between 10 couples that had 1 kid each; and 5 couples that had 2 while 5 couples had 0. It dawns upon me that I don't know any elderly childless people. The social cost of supporting someone who is completely alone vs. someone who has a kid they can depend on, even if only infrequently across large geographies, is probably a lot higher.
