I think others have hit on this, but I feel the need to chime in that this logic doesn’t really work.
If kids give it to kids, those kids then are vectors to give it to their parents, and from there to other people as those parents possibly interact while being asymptomatic.
This is going to be hard on families who aren’t prepared to work on one (or less) income - almost impossibly hard in some cases. However, the answer is not to send kids to school as a form of childcare - that defeats the purpose of trying to “flatten the curve.”
I feel lucky that my wife stays at home and works freelance in her spare time, so we don’t have childcare concerns (other than my wife’s sanity). For families who are able to work remotely, it will be tough to handle the logistics but they’re in a much better position than many others. Hopefully the rest of the people who have no choice but to try to work until/unless they get show symptoms will be able to ride things out. Aside from those who will suffer greatly from being ill (and their families), these are the people to whom my heart goes out.
