If there is such a thing as a PhD in Education, how can there also be failing schools?
It seems that if there are people who are experts in how to educate other people, that they should have a very high success rate and that even a few of them in the business of writing curricula, centralized study plans, and education procedures should show decisive advantages on they entire system.
If such people exist, what are they doing? Are they keeping all those education secrets to themselves?
I suspect the answer is really much more cynical. The education mill demands that their members continue to pay into the system throughout their careers and that eventually results in enough “credits” to “earn” an advanced degree. In most cases, they can even get other people to pay their fees (taxpayers).
