I want a "good cheese, good wine, good bread" price comparison metric. By that measure, my money in the US only goes like 1/2-1/3 as far as the same amount in France, since it takes about 2-3x the money to consistently match the quality of their bog-standard stuff in those categories. Usually a good bit of travel time, too, in the case of bread. :-(
[EDIT] actually 3x might be low on the bread. 3.5-4x, probably, around here, to get a baguette that's on par with your average Parisian one, for instance. You don't even hit "kinda OK" until $4 or so, and you're still not guaranteed to be getting something that tastes like a baguette at all, let alone a decent one, at that price. Croissants too. I've had exactly one in my city that was close to the real thing and it was crazy expensive. They burnt it, though. So close, yet so far.
