I believe Torque is correct, Our overlords will absolutely blame the virus on the market movements and the FED's reaction to printing 1.5 trillion to prop it up longer. One must wonder if it was entirely engineered and timed, the virus, the panic, the markets, the money printing. Idunno

Wouldn't put it past them if the WHO and other establishment organizations played it down until they got ready for some good old insider trades before ringing the alarm bells.
I'd be seriously surprised if there was anything that they could learn this late in that would shift the situation from "who cares" to "full panic". These issues are too well studied.

I think all the downplaying the WHO could do is already done. It was used up in the early stages to delay world awareness. Now they declared pandemic status already, so it's kind of a capitulation in that regard.
This doesn't mean the virus won't be the scapegoat for all the past and present market fuckery.
As for future fuckery, it can be justified by the ensuing trouble alone. No one says no to helicopter money.
