It depends quite heavily on the parents, in terms of what kind of results might be rendered. Not that I think the government deserves much involvement in the process there either, but it would be rather silly to assume that all parents are competent enough to provide a well rounded education.

And I'm not referring to their educational qualifications so much as how much time or effort they're even capable of devoting to that kind of an endeavor. Not that public schools today are a great option for anything resembling well rounded either.
