If the US had gone into lockdown in January, the ACLU might have sued the government in court (or another civil liberties org). The UAW would have fought GM on shutting down the plants (let alone the shareholders!). College students would be protesting encroachment on civil liberties. Businesses would have been screaming. The stock market would have gone into a tailspin. People in a free society would have flouted the orders out of civil disobedience. For all this stuff to actually work in a free country, a significant percentage of the population has to believe the threat and cooperate. I’m a highly educated person with a degree in molecular biology. I know all about viral illness and epidemics. Even I did not come around on the severity of this until last week (Despite reading all the articles!). It just pattern matched against all the other pandemics that were a big deal in Asia and elsewhere, but didn’t really impact daily life in the US.
