I think [the number of jobs that must be created monthly to maintain constant employment] is dropping. I would say now it's more like 130,000. And within the next few years, it might be down to 100,000...This is all based on research at the Federal Reserve on labor participation rates, which suggest that we'll be seeing, over the next 10 years, some significant decline from the current about 66 percent of the adult population is in the labor force. We expect to see that coming down and, therefore, the number of jobs a month we need to keep the unemployment rate is constant is likely to fall as well.
