The point of closing schools was not to prevent kids from getting COVID. The point was to help slow them from spreading it to more vulnerable, older family members at home. I'm eternally grateful that out of all the businesses and institutions (most of whom utterly failed to strictly adhere to closures), our local public school district did not screw around at all and implemented remote learning. It might very well have saved my (or my partner's) life--we'll never know. You can mitigate delayed school progress. You can't mitigate death.
