Quasi-independent since 1970, the post gets no public money. And yet it is obliged (as FedEx and UPS are not) to visit every mailbox, no matter how remote, six days a week. This has driven the average cost of each piece of mail up from 34 cents in 2006 to 41 cents. Yet the post is not allowed to raise prices (of stamps and such) willy-nilly; a 2006 law set formulas for that. So in effect, the post cannot control either its costs or its revenues.
[New phrase for hamstrung projects where the business wants to control all sides of the delivery triangle (cost/time/features) “Don’t postal the project.”]
