Let us stipulate that Professional Educators know what is best. Intellectually.
What a kid needs is someone who irrationally loves him & cares deeply about him & is willing to sacrifice everything for him. That's Mom and Dad. Even ignorant ones.

Which class of person should advise in the education & welfare of a child?
Which class of person should have final say?
