Don't agree with everything, but Daniel Quinn's essay on education is a must read.

Some excerpts...
"Of course, then, as now, everyone knew that the citizen's education was doing no such thing. It was perceived then--as now--that there was something strangely wrong with the schools. They were failing--and failing miserably--at delivering on these enticing promises. Ah well, teachers weren't being paid enough, so what could you expect? We raised teachers' salaries--again and again and again--and still the schools failed. Well, what could you expect? The schools were physically decrepit, lightless, and uninspiring. We built new ones--tens of thousands, hundreds of thousands of them--and still the schools failed. Well, what could you expect? The curriculum was antiquated and irrelevant. We modernized the curriculum, did our damnedest to make it relevant--and still the schools failed. Every week--then as now--you could read about some bright new idea that would surely "fix" whatever was wrong with our schools: the open classroom, team teaching, back to basics, more homework, less homework, no homework--I couldn't begin to enumerate them all. Hundreds of these bright ideas were implemented--thousands of them were implemented--and still the schools failed.
"During the Great Depression it became urgently important to keep young people off the job market for as long as possible, and so it came to be understood that a twelfth-grade education was essential for every citizen. As before, it didn't much matter what was added to fill up the time, so long as it was marginally plausible. Let's have them learn how to analyze a poem, even if they never read another one in their whole adult life. Let's have them read a great classic novel, even if they never read another one in their whole adult life. Let's have them study world history, even if it all just goes in one ear and out the other. Let's have them study Euclidean geometry, even if two years later they couldn't prove a single theorem to save their lives. All these things and many, many more were of course justified on the basis that they would contribute to the success and rich fulfilment that these children would experience as adults. Except, of course, that it didn't. But no one wanted to know about that. No one would have dreamed of testing young people five years after graduation to find out how much of it they'd retained. No one would have dreamed of asking them how useful it had been to them in realistic terms or how much it had contributed to their success and fulfilment as humans. What would be the point of asking them to evaluate their education? What did they know about it, after all? They were just high-school graduates, not professional educators.
"At the end of the Second World War, no one knew what the economic future was going to be like. With the disappearance of the war industries, would the country fall back into the pre-war depression slump? The word began to go out that the citizen's education should really include four years of college. Everyone should go to college. As the economy continued to grow, however, this injunction began to be softened. Four years of college would sure be good for you, but it wasn't part of the citizen's education, which ultimately remained a twelfth-grade education.
"And it should be noted that our high-school graduates are reliably entry-level workers. We want them to have to grab the lowest rung on the ladder. What sense would it make to give them skills that would make it possible for them to grab the second rung or the third rung? Those are the rungs their older brothers and sisters are reaching for. And if this year's graduates were reaching for the second or third rungs, who would be doing the work at the bottom? The business people who do the hiring constantly complain that graduates know absolutely nothing, have virtually no useful skills at all. But in truth how could it be otherwise?
"So you see that our schools are not failing, they're just succeeding in ways we prefer not to see. Turning out graduates with no skills, with no survival value, and with no choice but to work or starve are not flaws of the system, they are features of the system. These are the things the system must do to keep things going on as they are.
