This graph shows the performance of US industrial production for the past ten years. The "cliff dive" of the Great Financial Crisis can be clearly seen, which bottoms out at 87.4125 in 2009-06. A quick recovery follows for a year, and then steady recovery until it peaks again at 105.9906 in 2015-01. But since then, Industrial production has slowly declined. Why? The 2015-01 peak was not much greater than the previous peak of 105.7290 reached in 2007-11.
