The irony of the situation is that parents who are educated and intelligent and, therefore, great candidates to be good homeschool teachers also realize that they are not up to the task of homeschooling their children.
An educated and intelligent parent taking personal interest in a child's education vs. an overworked or underperforming (cannot be fired, unions) teacher lecturing to the lowest common denominator of 30 students at a time. I know which one I'd bet on.
