Holt is not a particularly good figure to cite to back up your assertions. "Education" books are like most "business" books, very little research and data to back up scores of anecdotes. This doesn't automatically make him wrong, but many of his ideas have been overturned and refuted by actual research and investigation.
However, your point stands and we are in agreement with the fact that there is no political will to expend the resource required to improve educational attainment.
