An outstanding post at Catallarchy on the anti-voucher argument with respect to education.
Why are vouchers bad for schools, but good for virtually everything else, from food stamps to Social Security?
(For the record, I am against federal vouchers because I am against any federal education spending. It's a local issue. Locally I'm also against them, because I think education is not an appropriate role of the state. I'm willing to accept local community education, but that ain't what we got.)
