The "expert" hired in from across the Atlantic glibly dismissed the price of a stamp as being less than a bar of chocolate. As I remember it, chocolate is a luxury food that's not essential. The Post on the other hand is very much an essential service. Try getting your mail order purchases by e-mail or important legal documents satisfactorily signed. Like it or not, the postal system is still the lifeblood of commerce no differently than the National Grid or the motorways.
Is this a fiendish plot to make privatisation look like a good idea? Lots of potential revenue for a would be buyer with the opportunity to then drop the price; just showing how much more efficient it is under private ownership.. In the meantime, already squeezed commerce can happily go to the wall and die. Maybe I'm becoming cynical in my old age.
