Another big up to BOF for the Orwell quote - and, yes, it's disgusting that the same old patronising crap is still being rammed down our hungry throats.
... and, thinking about the food value of crap, this is a more interesting question than it might at first seem: why is there such a large price difference [in Macdonald's]? Are there different country polices?
Yes! Macdonald's uses a very precise algorithm, which takes into account the average income of a country, income by sectors, and food prices. So clever is this, the US government - and most others - use it as a guide to standards of living. Coca-cola used to do the same, but I'm not sure they still do; the price of a Coke doesn't seem to vary as much as a Big Mac.
If a French Macdonald's (ooh, it sounds nice in a French accent!) is fearsomely expensive compared to a British one, this would suggest that the price of food and the standard of living are higher there. Just going by those EU/UN standard of living charts, that would seem to be right.
Still off topic, has anyone else noticed that Italy's suddenly got wildly more expensive, while Germany seems to be cheaper these days?
