The decline in public education (as witnessed by drop-out rates, test scores, remediation needed before college, etc.) since the early '70's is a little hard to miss. Isn't the drive toward centrally directed uniformity, either in curriculum, methods, or testing, is so contrary to human nature that it will never work?
We have proven that the supply of quality goods and services is best assured by letting a free market inspire ideas and hard work; why do we insist on having education, which is a service little different from restaurants and gas stations, controlled by distant bureaucrats and ivory-tower theorists? We don't make everyone wear the same type of shoes or watch the same movies; why should we make them go to one-size-fits-all schools that are so reminiscent of the Post Office and DMV?
