Isn't hindsight a wonderful thing? I mean to know how the decisions you make today, and the words you say today will affect history months and years down the road?
Closing schools and businesses may not have been the best decision, but it was based on information known AT THAT TIME.
And even if we KNEW kids wouldn't be affected by Covid, what about the teachers, the cafeteria workers, administrators, bus drivers, janitors, and other adults that are necessary to conduct school? They're on their own?
Its easy for people to say "you made the wrong decision" months and years after the decision was made, thanks to hindsight, which is always 20/20.
