Just redirect the funding from whatever source to the children. Then let schools compete for students. It's just applying competition to schools like any other business.

If that had been the plan when my 5 kids were in school, then the fair market value of teaching at home (which saved the state half a million dollars) would have eased the burden considerably. It would change the calculus when making the financial decision on which choice to make.

Give the parents $10,000 per child and the responsibility to educate their children. At that rate, most taxpayers would get tax relief.
