That's true, yet there are plenty of regional languages in France (Bretagne), and don't they speak some kind of fucked up French/German hybrid language in Alsace? It's not indicative of a 'divide', especially when the number of speakers are so low. Economically, France doesn't really have a divide to speak of. England and Italy do.

Well, there is a big divide between metropolitan France & rural France, but that's more of racial thing.

The economic divide between north & south France isn't as big as it was when I used to vist my grandparents village near Aix-en-Provence, that's for sure. The south was really quite backwards up until the 60s, mechanisation of agriculture didn't really happen until well into the late 60s, early 70s.
