I think the author is confusing the Parisians or those from the South with 'normal' French people! I live on the Breton coast and am happily surrounded by the locals; farmers, fishermen, builders and other manual tradesmen. None of what I have read in this book sounds remotely familiar to these wonderful, friendly, kind people that I have grown to love and respect. France is a big and diverse country and every region and its people is very different so I'm confused as to where the material for this book came from.
I have read virtually every book on living in France and its people and this one didn't come close to reality. I was bored very early on and it didn't get any better.
