Why? Because of reasons I've already stated in addition to that my child doesn't need the President of the US tell her what teachers, principals, parents and role models have been telling children for years. The importance of a good education. Yes, other Presidents have delivered the same messages, while personally visiting individual schools/classrooms, not this way.
Oh, so you wouldn't mind if he took time from that Oval Office that you think he's so unfamiliar with to personally visit classrooms? Wouldn't a nationwide address to schools be a more
efficient use of time?

And simply because your daughter hears that message from other role models, she doesn't need to hear it again? Isn't it a lesson she can't hear
enough?? I think it's one that bears repeating, and one they can't hear enough. Given their constant exposure to rap music, violent video games, other kids who drink and smoke and use drugs, they certainly could use the repetition of life's positive lessons.
