There are actually two recessions:

The first is the cyclical one, the one that inevitably comes and then inevitably goes. There's plenty of evidence that intervention can shorten it, and also indications that overdoing a response to it is a waste or even harmful.

The other recession, though, the one with the loss of "good factory jobs" and systemic unemployment—I fear that this recession is here forever.

Why do we believe that jobs where we are paid really good money to do work that can be systemized, written in a manual and/or exported are going to come back ever? The internet has squeezed inefficiencies out of many systems, and the ability to move work around, coordinate activity and digitize data all combine to eliminate a wide swath of the jobs the industrial age created.
