I thought you would be interested in the following story from The Wall Street Journal.
For more than three decades, Chinese women have been subjected to their country’s brutal one-child policy. Those who try to have more children have been subjected to fines and forced abortions. Their houses have been razed and their husbands fired from their jobs. As a result, Chinese women have a fertility rate of 1.54. Here in America, white, college-educated women—a good proxy for the middle class—have a fertility rate of 1.6. America has its very own one-child policy. And we have chosen it for ourselves.
Forget the debt ceiling. Forget the fiscal cliff, the sequestration cliff and the entitlement cliff. Those are all just symptoms. What America really faces is a demographic cliff: The root cause of most of our problems is our declining fertility rate.
