Niall Ferguson, a Harvard professor from across the pond, writes in the Sunday Telegraph that he's having to dig deeper in his pockets to taste the Philadelphia cheesesteak.
The historian, in a piece on population growth and food production, notes:
When I wanted a Philly cheese steak in the States last week, I had to pay through the nose. That's because cheese inflation is 4 per cent, steak inflation is 6 per cent and bread inflation is 10 per cent. (American steak is now 53 per cent dearer than it was 10 years ago.)
