South Korea showed that you don't need to shut down society, if you act early enough and have enough test kits. Then, you can find who's infected, do contact-tracing, and isolate only those who are truly infected and those who were exposed to them.Not sure turning everything off is the right solution. Perhaps we should be looking at going back to 75% normal without restaurant dining rooms, big crowds, ect... But everyone goes to work unless sick and we isolate the vulnerable. Mobilize and produce for the medical needs that are coming.
Anyway, the US failed in both areas and now we have to fight it the hard way.
