How might money be used in a more productive system? David Monk imagines a public educational system in which it is possible to link benefits received with costs borne. Such a system would require novel ways of alloying teacher knowledge, sometimes through technology that increases the number of students who can learn from an expert. Excellent teachers would then have higher status and be paid more. Schools and districts would have performance data on every student and classroom and, when problems are apparent, could rush in help to prevent students from losing ground. The instruction available in any community would improve over time as districts identified more effective schools and instructional programs and abandoned less effective ones.
