I don’t think you can dismiss the economic impact as “parents wanting to be relieved of the burden”. People need to WORK. On a macro level, we need people back at work. We need them making stuff, earning money, spending money. There’s a lot of people who can’t work if there’s no where to send their kids. And if stay closed for another extended period, we are either paying tons of people for doing nothing, or laying off even more (lots of people, like teachers, are still working from home, but others are really having to scramble to appear busy (bus drivers, cafeteria workers, learning specialists, etc.)
The educational impact is also no joke. There’s a lot of slack in the system, and I honestly believe that we can “catch up” from having lost half a semester. But I think it will take two full years for most cohorts to do so: today’s 3rd graders will be testing behind until at least the end of their 5th grade year. Another semester and we are reaching the end of that slack.
Finally, as mentioned by Fretful Porpentine, public schools have long taken on the job of front-line social work: we monitor kids for abuse, provide meals, etc. We put kids and families in touch with other social services. Fuck, every high school I know these days has a “closet” somewhere for kids to pick up food and clothes and toiletries if needed. As the social safety net has stretched thinner, schools have taken on this role.
That said, before we open schools, I think there are some realities that need to be dealt with.
If it’s only safe with strict social distancing, it’s not safe. Masks could probably be enforced, but not distancing. LOOSE social distancing is probably an achievable goal, IMHO. But there would be lots and lots of lapses --which still is better than nothing.
There’s a real problem with existing illnesses and allergies. If every teacher or student who has any sort of cold or allergies has to stay home until they are symptom free, it’s going to be a mess. It’s easy to say “stay home if you are sick”, but I have a few kids every year that are literally snotty every day, because they have allergies. I have at least one mild cold a year, and from “first trace of a sore throat” to “no symptoms at all” is seven days.
What’s the plan if someone does test positive? Close the school? Send home contacts for a two week quarantine? In high school, at least, a kid may share classes with 100 other kids. A teacher probably sees 150.
If we decide surface transmission is a thing, it’s a huge problem. We don’t have the staff to clean the building thoroughly; we don’t have enough books for kids not to share. We don’t have enough working sinks.
