If you give companies a big shield against cv19, how will you incentive them to give basic and necessary protections to workers? These low wage job workers are really vulnerable because they mostly don't have money saved up and have to work. There's the issue that you can't know where someone got it, but in these big factories where huge numbers of people get it and it goes through the factory, it came from there at least for some of them. I think we're just screwed. Big business wants these shields, workers in the us don't often have a good outcome in that situation.
