But hiring at that rate is unlikely. That's exactly why the Federal Reserve predicts it will take until some time in 2015 to bring the unemployment rate down to 6.5%.
Rosenberg thinks even that is optimistic though. If job growth continues at its current pace of 150,000 jobs a month, it could take until 2018, he said.

All of these predictions factor in population growth but hinge on one key metric: the economists are assuming 63.6% of the adult population will be participating in the labor force, meaning they either have a job or are looking for one.
The unemployment rate could fall more quickly if more workers drop out of the labor force, which happens when people retire, go to school or give up on the job market. In that case, the Fed would probably not view a falling unemployment rate as a good thing.
Fed Chairman Ben Bernanke made clear Wednesday, that although the central bank announced the 6.5% threshold, it "by no means puts monetary policy on autopilot." The central bank plans to consider "a range of labor market indicators," he said.
And getting the unemployment rate back to 6.5% is only a start. It doesn't represent a full recovery.
Before the recession, the unemployment rate was 5% in 2007.
Every month, the Hamilton Project, an economic research arm of the Brookings Institution, publishes a "jobs gap" calculator that estimates just how long it will take to get back to that level, assuming the only major job market dropouts are Baby Boomers who are retiring.
But you may not want to hear the answer. At the current rate of hiring, the Hamilton Project estimates it would take until 2025 to get back to a pre-recession job market.
