I don't think "of course" belongs in that sentence. Not everybody feels so defeated, or would feel better seeing the manifest evidence of societal dysfunction (if it happened, I've not foreclosed on it) emerging from black boxes concealing different interpretations of a good and complete education as numerous as there are families.

And I can't argue with your position on how often things are fixed. It wouldn't matter what evidence I found, the goal post would just move a little bit farther. Sure, "it happens sometimes," but never enough to satisfy.

But I can counter with, how often can you fix broken homeschooling that has no auditing or oversight?

Never. Not even sometimes.
