I might be missing something here, but since when has a post office been the key to the survival or cohesion of any community? OK, if it's also a village store or a pub, I accept, and it's important that old folk can pick up their pensions in a relaxed and reassuring setting. But most post offices have no social function whatsoever. They are shops where you can buy all sorts of stuff you can buy anywhere else. What exactly is the rationale for massive public subsidy?
