You think that home educating kids is something new? What do you think happened for likely millions of kids before the public indoctrination centers were established?
And I'm opposed to any proposition that can only be defended on the terms you've chosen.
What does that mean? That you oppose parents selecting their children's curriculum?
Instead of tax credits or any kind of vouchers, they should make school a pay as you go proposition. I paid way less in curriculum costs for my three kids per year than I do in school taxes each year.
What happens if they don't want to pay, and don't care if their kids get an education or not?
