At least 895 people died of Covid-19 yesterday in the United States; I say 'at least' because poor test coverage guarantees the number is much higher.

895 annualized to a year is about 330,000, which puts it above all other causes of death in the US except cancer and heart disease, higher than:

   Accidents (unintentional injuries): 169,936
   Chronic lower respiratory diseases: 160,201
   Stroke (cerebrovascular diseases): 146,383
   Alzheimer’s disease: 121,404
   Diabetes: 83,564
   Influenza and Pneumonia: 55,672
   Nephritis, nephrotic syndrome and nephrosis: 50,633
   Intentional self-harm (suicide): 47,173

More alarmingly, the growth:

Can Covid-19 keep spreading and eventually kill 1/3 of a million people? Easily: one percent of the US population is 3.2 million.

I know you're not putting forward an all or nothing proposition. I also know that the economic impact of this pandemic will be enormous, more enormous than almost anyway can currently predict, whatever our 'lockdown level'.
