across the entire country on a regular basis. That means hospitals will overflow, schools will shut down in person, and more. That's where my 2 year question came in.

I agree that we will all be exposed to some variant at some point. Hopefully it evolves towards a less deadly strain over time. But you have this weird fixation on not doing anything that doesn't work perfectly to mitigate spread. Those mitigation actions may be the difference between keeping kids in school vs sending them home. Improved ventilation is great, but any school that had the funds, willingness, and means to fix it has already done so. Unless you want to argue that schools should just power through massive outbreaks (which isn't going to be tolerated), there's no real alternative. I gave you evidence that masks in schools make a difference in keeping kids out of quarantine in my town and we're seeing it all over the southeast. Vaccination may not be perfect either (though I'm optimistic that an mRNA booster properly coded for delta could get much closer to the original shot), but if we don't get boosters updated for the new variants we're just going to see the continual cycle of deaths at what to me are unacceptable levels.
