I agree with you that home school is not scalable, but for different reasons. We certainly cannot rest on the assumption that every teacher is a good teacher, and with a $40 internet connection and $500 computer, reasonable access to learning material is virtually guaranteed. Furthermore, I don't think the presence or absence of diversity will have much impact on the most desirable measurables of child rearing, which in my book are: ability to support one's self, being a good citizen (not stealing or hurting people), reading ability, and grasp of basic primary school subject matter. The reason why home schooling is not scalable is that parents of under-performing students are predominantly poor, and are either single parents or if there are two of them, both need to work to make ends meet.
