One hypothesis is that this Covid-19 pandemic is being used to usher in the depression that may have taken some time to unfold on its own. Given the profligacy of the central banks over the last decade, it was obviously going to happen. Bubbles are always searching for a pin.
The pandemic gives the powers-that-be cover to blame it on a red herring, rather than the actual cause, i.e. the Central Bank.
This is good because most people don't understand the schemes of the central banks and thus, would not grasp why the depression was happening. The pandemic makes for a very palatable story. "The government HAD to shut down businesses, forcing us into a depression. It was unavoidable. And by the way, the central bank isn't lowering rates fast enough."
(This was bullshit, by the way. The problem was that the central bank kept rates far too low far too long. But the average person can't grasp that.)
Blaming the bank (a little bit) gives Trump cover to phase it out (awesome!) or nationalize it (a terrible idea).
