The logic of lockdowns: were big stores actually safer

I know they gave us the answer that getting everything in one place is better and bigger stores have better ventilation blah blah blah but do you really buy that?

A lot of people praise and defend our lockdowns and at the same time preach about taking down big corporations meanwhile the corporations got insanely rich off of it and poor people got poorer and lives ruined

Where is the real logic? Do we truly believe we had to let Walmart stay open but couldn’t let the little fruit store stay open?
