Well.....do I have to plug in local community?
Or - better yet, since the State bumps into an amendment no matter which way it turns, is the State in such a conflict of interest that separation of school and state is necessary? Again, the Constituionality of public schools is questionable.
The real question, as you correctly point out, is whether the government should be involved in education.
The 14th Amendment assures that nothing will change. Scalia, in a recent speech, told the audience that there was very little the federal courts could do to stop the increase in federal regulation and also pointed out that it was in no federal judge's interest, including his own, to limit federal power. His subtle point was that if federal encroachments are to be resisted, it is up to populist action by the states to do so. (Thanks to Am. XVII, the U.S. Senate no longer fills this role).
IMO, the federal constitution is no longer sufficient to guarantee limited government. You should read the Confederate Constitution. It is a remarkable document, with the exception of allowing slavery (though it also banned the importation of slaves).
