While political leaders and corporate CEOs, focusing as usual on the quarterly return, call for "workers for the new economy," their educational reforms are producing just that: students with a grab-bag of minor skills and competencies and minds that are sadly uneventful, incapable of genuine intellectual achievement and lacking any sense of continuity with the historical and cultural traditions of our society. Their world is small, bleak, and limited; their world will become ours. [David Solway, "The Turtle Hypodermic of Sickenpods," Quebec, 2000]
