@Walter Hinteler,
Sorry, I don't understand. My take is perhaps simplistic but I think Germany reformed its labour laws with good results, and we should do the same. France is not in decline demographically or culturally. In fact, our culture is more vibrant and less submissive than elsewhere if one judges by these cartoons. But the country is de-industrializing. There are other reforms that would be important but labour laws would be a key one. We could discuss in greater depth, on another thread I guess.
My point is: history is not deterministic, there are no "laws of history" that say that powers must rise and fall in one nice parabolic trajectory. Any nation can rise and fall and then rise again and fall again... The decline of France (or of Europe, or the of US for that matter) is not unstoppable. It is not 'inexorable' or 'written' anywhere. It simply results from a lack of courage and clear direction.
