Because I'm actually pretty terrible at math! Ha! And yes, we do have online high school in Utah, but it requires teachers, so you can't just increase their workload 50%. Because online teaching is still teaching and students still need help, feedback, etc. That's why during the stay at home, they are asking all teachers to teach online, the best they can. I agree with you that it is hard for a teacher to manage in class and online students, and that's why you can't really ask them to do both.

But really, my post is not about my family ... that's just an example to show that a healthy middle-aged family would need to stay at home ... not just the retired folks. More important is the other things I said in my post ... it's the large percentage of Americans that are either at risk themselves, have an at-risk person in their family, or are caring for an at-risk person. You start adding it up ... and you're probably talking like half the country. Or a third, or some other large number. It's really hard at that point to simultaneously run systems and institutions where half the people are there and half have to be serviced in their homes, or be able to work from home, or be schooled at home, or whatever.

I'm not against trying it, because I acknowledge the economic devastation we're experiencing. I just think we need to be honest that it isn't that easy to tell people to self-isolate, and really pretty impossible to isolate them completely because of all their family members that are connected to them. So the death toll would go up as a fact of the situation. And it wouldn't just be old people. We'd need to acknowledge that and be ok with that.
