Well if you want to go down that route - basically yes, French culture is so unimaginitive and conservative that if it hadn't been for imimgration from West and North Africa it would basically be a sad pastiche of what it was in the 1950s. Basically everything interesting and creative that happens in France these days is the product of people with Arab or West African roots.
Obviously there hasn’t been a non-degenerate art movement in the West since Art Nouveau, but at least when I think of “France in the 1950’s” it gives me a definite idea. When I think of French culture today, all I can think of is
Cuties.
