Given that markets around the world have crashed before the epidemic got very far at all it is highly likely that they would crash if the epidemic got worse.
But you can show us all how much you know, just start trading in the market and let us all know how it turns out.
Why do people like you create strawman arguments by putting words in other people’s mouths? You can’t envision a response that includes many of the current measures without the draconian one size fits all prescription? Like mandating closing retirement homes and caregiving facilities to visitors, mandating work from home solutions where possible, massive media outreach to educate the public on health risks for given demographics, closing the borders and ports to cruise ships, etc. Sure the economy would have taken a hit but it didn’t have to be fatal. Instead they’ve flat pulled the plug and are digging a multi-trillion dollar hole.
