I'm really not sure which approach I prefer. If you contextualise it to a company, it's crazy to think you could develop an effective system by having top-level management of a country-sized company devise a monolithic, cookie-cutter plan that gives teams zero autonomy or ability to use their personal judgement. You have to allow the men on the ground to innovate, and adapt to their specific problems. The cost of autonomy is that some teachers will teach creationism, but it also means the people who are closest to & have the biggest stake in the learning of each child have control over how that kid develops, which in general seems better aligned with incentives.
