Cut out all education, ignorant people are much easier to control. The Catholic church understood this and that's why they didn't want the Bible put out in a form that the lay person could own and read.
With a less than 50% success rate, a cabal of indifferent union controlled teachers appear to have "cut out (damn near) all education" quite nicely on their own accord.
You can bet this Rhode Island community is not an isolated case.
Unless I am misinterpreting your comment, apparently, for you and a few others, it's too much to ask for a better than 50% success rate from ones tax dollar.
