if we'd been more levelheaded, we would have suggested the public should either
1) physically distance, or
2) wear a mask
in enclosed spaces and face-to-face situations.
if you're an essential worker or particularly vulnerable, you'd do both where possible. that's it. that likely would have provided all the risk reduction we needed to get the spread under control.
the message would have been simple, the effects likely as good, and we wouldn't have left a hundred million poeple on the edge of (or in) economic and psychological collapse.
but that doesn't punch the emotional and neurochemical pathways the way politicians and news peddlers want.
