Forget how they're going to learn remotely, who is going to watch and feed those kids?

Their parents, who are about to be either working from home if they are white collar, or laid off if they are blue collar, because local economies and services take a nosedive during a pandemic. We're in the middle of this in Seattle - service workers aren't being called in, or are getting laid off.

And if you aren't in either of those categories, you should have a friend or relative who is, who you can ask to childsit.
