Today I ran across a piece in The Guardian about Japan’s demographic crisis. The piece, entitled “Why Have Young People in Japan Stopped Having Sex?” explores an interesting phenomenon unique to modern developed states–the tendency for birth rates to collapse as a civilization reaches higher levels of economic output. This is not a Children of Men scenario–affluent peoples are not becoming biologically infertile. Instead, we see a decreased desire on the part of citizens to have children or even to get involved in romantic relationships of any kind. What’s driving falling birth rates, and to how are they a problem? That’s my subject today.
