He should join the ranks of Oprah and simply build a school somewhere and push his ideals in his own building with willing volunteers. Another person from the business world is taking her millions and building a school in an inner-city I grew up in. Her selection of a curriculum is a clear indicator of how uninformed decisions about curriculum can do more damage to students than good (let's just say she chose one based on principles from Pavlov), no matter how well intentioned the person is. This trend is making me ill.
