The French flee their countryside for the city, leaving the field wide open for middle-class English people to come in and gobble-up property at ridiculous prices. If this trend continues, rural France will be populated entirely by the English and we'll be well on track towards re-establishing the glorious Angevin Empire.
In the reign of Henry II (remember him from the Lion in Winter?) the Kings of England (who were Frenchmen really) controlled a coastal strip that ran all the way from the Scottish borders to the Pyrenees. It was a geographical unit that made as much sense as most modern nations. I want it back. I want it back NOW!
