The correct thing would be to nationalise them if they go bankrupt, not to bail out the investors that earned money with the explicit expectation of risk.
And I say that having lost 10k in stock value in the past month. Still my fault and my risk and I don't deserve to be bailed out for it.
No insurance policy covers war. This is pretty much like a war. It's uninsurable because it affects everyone.
Bailouts in 2020 are not gifts to the reckless rich like in 2008, they're like the Marshall plan.
