If all people learnt in school was how to do boring repetitive tasks and submit to authority, where would innovation come from? The country would stand still if nobody had the knowledge to invent the next generation gizmo, or work out how to make grommets more cheaply or in more useful shapes. If nobody learnt how to play music or write novels (or produce tv programmes) we would all be reading the same books over and over, and watching repeats from the days when those things were encouraged. There would be no fashion, no food development, no advances in medicine. We could either sink back to a less advanced way of living or buy in expertise from countries who do educate their populations, and act as service workers for them.
You have a very limited understanding of education, David, not to mention a very limited grasp of much of ‘the world of work’. You seem to see both as homogeneous environments with no scope for development. A basic understanding of, say, history, psychology or sociology would show you that many intelligent people forced into repetitive work with no opportunity to change their lives become alienated and resentful. Society then has to choose between harsher policing/ government and finding more enlightened ways to prevent revolution. Presumably you would deny people the opportunity to study those things though, as they don’t have immediate and obvious application in what you see as ‘the world of work’?
