I would have liked that when mine were going to private school. I wonder though if that went through would it drive up the cost of private school with so many more people able to send their kids.
I also heard a plan that would let the child only take a portion of the money with them. For example, if the school spends $8k per child per year the child could take $5k with them to the private school. That way the school still gets money and has less kids to teach. Win win.
Supply will increase to meet demand.
