It won't work fint - to get the "good" teachers, the "good" schools are going to have to pay them more. This will require more funding (ie, a top-up by parents on the average cost per student you want the govt to give you back for opting out).

This is just going to create a wider gap between elite and mediocre schools based on the wealth of the parents of children attending those schools - even wider than the current socio-economic gap that occurs.

You may think this is ok, but I don't. Education (at school level) is a public good, and I don't complain about what is spent on it out of my taxes.

Why don't you compare America's education spending (total govt spending) against military spending. That always staggers me...
