A Coca-Cola Zero soft drink in a French restaurant in Paris (France) is typically 5 to 6 euro per 50 cl (even in "normal" restaurants, not in the Champs-Élysées nor the Eiffel Tower), while in Barcelona or Madrid (Spain) is 1.50 to 2 euro, being exactly the same product. So go figure with wine, or buying a lunch (2x-3x more expensive in Paris than in Madrid or Barcelona). In my opinion, that will be good for French people: they already do massive near-dumping with milk production because of their high productivity/efficiency, and they'll have to learn how to be efficient producing wine and fruits.
