Virus Mobilization Good morning. Corporate America says it will play a bigger role in fighting Covid.

And successful wartime mobilization in the United States has always involved much more than the government. The best example is World War II, when private companies like Ford and General Motors quickly overhauled their operations to contribute to the war effort. In the fight against Covid, however, the private sector — with the big exception of pharmaceutical companies — has done relatively little so far. It has not made a major push to persuade Americans to remain socially distant, wear masks or get vaccinated as soon as possible.
