If education advocates want a larger share of state appropriations, they must acknowledge it often requires offsetting cuts in other government programs, particularly social services. So far, school funding proponents haven't made that case, preferring to instead demonize tax reductions. That's been a losing strategy.
More importantly, in their quest for greater school spending, proponents have often failed to answer fundamental questions: Exactly how will extra money be used, and how will that improve student performance?
Until advocates give a compelling response, their political successes will continue to be limited.
