Hmm.
I think what Libertarians favor is a free market education system, the education system would still be funded by tax dollars.
Instead of going specifcally to fund public schools, Joe and Mary Blow would have the options of using tax credits to purchase tuition at any public or private school of their choice. So, public and private schools could "compete" for your educational tax dollars.
I agree with Colin though, in practice the tax credits do not provide Joe and Mary Blow with enough money to afford a "premium" private school. So, they can only afford parochial or public schools. I dislike on the grounds that essentially the state funds religious instruction.
For all the religious zealots who support the idea, I laugh heartily. They will be the first to line up against the Islamic, Nation of Islam and other non-christian religious schools that will form to take advantage of the money.
Also, I think there are economies of scale to public education. Although I am a Libertarian, I also believe that the vast majority of people are stupid. Even though they have a right to do what they want, the vast majority will make stupid decisions. I don't think Joe Blow should be able to make a decsion that adversely affects Joe Blow jr.
