You can't really look at a past study of unemployment effects and expect it to be anything like what we're about to experience; we literally have no idea.
The economy cannot be paused without massive stimulus to keep it afloat (and no, the current stimulus isn't keeping it afloat). Some companies are entering bankruptcy as we speak. They aren't coming back.
Good system, eh?
A very large number of industries, companies and communities will be permanently wiped out from this.
There are also industries growing, and industries that will be created. And some of the industries that may be permanently eliminated may be a net positive -- cruise lines are a complete blight.
I don't know what the net-net will look like, but it's important to push back on the assumption that economic downfall will be all negative in terms of lives lost.

Unemployment is deadly. The mortality rate while in poverty is over 2.5x.
