Postal engineering and the wider value of infrastructure

A disagreement over postal-service profitability leads to the argument that a communications network can help other activities earn money without itself producing a surplus. The British postal service's engineering role in wartime computer construction supplies a historical example of expertise extending beyond letter delivery. Clarke argues that governments should be sized around the functions they are expected to perform, including infrastructure. Another participant contrasts infrastructure benefits over decades with shorter commercial investment horizons. These are arguments for judging a network by its wider service and capacity, with differing views about acceptable losses.
