Reduced, if only figuratively, to shaking the dust from their piggy banks, government financial types from California to Copenhagen have turned their eyes to that ever-elusive dream: Dragging those who have fled into the shadow economy back out into the open where they can be induced to keep the machinery of the state running just a little bit longer.

Could governments be chasing away the objects of their interest with excessive attention?
