Here's (via https://pluralistic.net/2020/06/30/deafhood/#diagnosis-cure) an admirably compact diagnosis of the malady afflicting capitalism and a suggestion for a cure from Yanis Varoufakis:

In 2008, we had an "endogenous" crash, caused by the finance sector itself. Governments gave them trillions, but "this liquidity did not turn into actual investment in the real economy."

"Banks recovered, the oligarchy found themselves with appreciating assets, the majority our there had to face harsh austerity. This boosted the disconnect between the world of money (that was doing well) and the world of the real economy (which was not)."

Now we face an "exogenous" crash, caused by the pandemic, but, "when Covid-19 arrived on the scene, it acted like a pin that bursts a gigantic bubble. Reflating this bubble, in the absence of public investment, will not be possible however much money Central Banks pump in."
