Conservatives aren’t giving up on their plans to destroy the public school system. Their weapon of choice: Vouchers that would allow parents to use public money to send their kids to private school. The result, as they well know, would be to suck money out of the already underfunded public school system and undercut the system's ability to provide quality education. That would lead to even more students and money leaving the system, which would further worsen the situation—and so the downward spiral would go.
