How much money does a government school monopoly need?

"In Oklahoma as elsewhere, there is no upper limit to demands for more money from a government school system that has consistently squandered regular spending increases," Greg Forster writes. "It’s been the same story year after year, for decades. However much we spend, it’s never enough; however big the spending increase is, it’s still so small that expecting to see any results from it is unreasonable. 'Adequate funding,' like Neverland, is always somewhere far beyond the horizon, no matter how far we travel."
