The Supreme Court decision on March 6th in the case of Rumsfeld v. Forum for Academic and Institutional Rights (FAIR) should be a lesson to libertarian supporters of government-funded school vouchers. The Court ruled that colleges and universities that accept federal funding cannot bar military recruiters from their campuses. I believe the old saying is: "He who pays the piper calls the tune." Government-funded vouchers will certainly increase federal control over the private schools that accept them. Why do some libertarians think that vouchers are an exception?
