> As your kids get older, it is harder and harder to give them a proper education. By the time your kids are in middle-school, subjects get harder for a parent (or pairs of parents) to cover in a way that does each subject justice. As a kid, I attended mostly private school, but when public school-educated parents express concern that they wouldn't be able to competently teach standard middle school subjects, that sounds much more like an indictment of public schooling than of the at-home variety.
