It's not enough. Just as the head of the Chicago teachers' union responded when asked how much does education require. NO amount is ever enough, in the fevered minds of the leftists. So, why stop with $9? Make it $50/hr! Make every one rich in one fell swoop!
Never mind that this scheme demonstrably hurts young minorities. Pay no attention to the fact that this idea is illogical and unsupported by economic studies. It sounds good and it gets me votes!
