> I think that metaphor is not very apt, because it doesn't capture the drag on future work. Bridges and roads are stationary.
Poorly maintained roads and bridges ARE obviously a drag on future work, since nearly all other work depends on them for transportation, it drives up costs (eg. potholes start to drive up maintenance costs for vehicles and increase commute times), and reduces tax revenues (whether it is through depressing real estate prices or other mechanisms).
