France can survive Nazi invasion but not Global Capitalism
That is one of the messages I take from this film, although admittedly the was nothing about the Nazis in it, I am just using that as a contrast, and there is much more to it than that.
The daughter Adrienne lives in two of the citadels of Global Capitalism, i.e. New York and Japan, and is going to marry an American (Clint Eastwood's son to boot!).
The younger son Jérémie is off to the rising power of Global Capitalism, China, where he is to manage a mass production shoe factory. His children will be educated in English, the language of Global Capitalism and not in French thereby cutting them off from their cultural roots.
The oldest son Frédéric, he is the only one who stays in France, he gets to sell off the house which is the family heritage, the other two enthusiastically sell off the family treasures to fund their lifestyles.
I suppose France had a good innings.
