Earlier quoted context omitted.
There is a resolution to the paradox. Masks do work (especially when worn correctly), but the net-optimal place to put them to work is keeping medical personnel up and functional. Have spare masks? We are trying to get them to the people who need them most: https://findthemasks.com/ We are presently listing hospitals accepting small-scale donations in 28 states, growing fast.
Except that wasn't the actual message coming from the Surgeon General. The original message appears to intentionally obscure the fact that not only does the US not have enough masks for our civilians, we also don't have enough masks for our health care professionals.
The government already misleads the public when it exaggerates things like the actual threat of terrorism to the average American, at least this time it is lying with some sort of societal good in mind.
