And it does flatten the curve -- but not nearly enough.  The death rate from the disease is cut in half, but it still kills 1.1 million Americans all by itself.  The peak need for ventilators falls by two-thirds, but it still exceeds the number of ventilators in the US by eight times, meaning most people who need ventilators still don't get them.  That leaves the actual death toll in the US at right around 2 million deaths.  The population of Houston.  Two civil wars.  One-third of the Holocaust.  Globally, 45 million people die: 7.5 Holocausts, 3/4 of World War II.  That's what happens if we use common sense: the worst death toll from a single cause since the Middle Ages.
