Give parents a refundable tax credit in an amount sufficient to send their daughters and sons to excellent private schools.

Subsidize private schools to that extent and then they become public schools in everything but name. If the government foots the bill then they get to say how they're run.

No they don’t.

The refundable tax credits go to the parents.

The parents then defend the schools from government control.
