Muriel Barbery said this quote

Maybe the greatest anger and frustration come not from unemployment or poverty or the lack of a future but from the feeling that you have no culture, because you've been torn between cultures, between incompatible symbols. How can you exist if you don't know where you are? So you burn cars, ecause when you have no culture, you're no longer a civilised animal, you're a wild beast. And a wild beast burns and kills and pillages.
