For primary school, it's a lot more about the child care than it is about the education. At that age the most important thing is safety and enrichment, something provided equally well (well, probably better) by unschooling. Something all my neighbors seem to be doing right now.

We could come out of this with a generation of kids that have learned better how to play and how to let boredom cultivate creativity. Depends a lot on the home situation though.
