Education, or perhaps the better word is training, is the most important method of good governance in the unitary state because there is no market or public to discipline administration. Control of the mind is not just about dissent but about performance. Free speech rights undermine the unitary state as an effective organ by making it impossible for the state to perform. By contrast, market economies function well on very little organizational education — training — because of the discipline of the market and the voting of feet.
What I mean by training is the altering of human preferences to ensure that the trainee makes the most efficient set of credible threats.
