no, theres more to the riots than that - its growing resentment on the part of 1st 2nd and 3rd gen immigrants living in france, subject to the double peine rule, subject to harrassment, intimidation, and abuse from the police because they are not represented, do not have a say. Sarkozy was complicit in allowing this behaviour to go unchallenged and this is why he is resented as a right wing politician. Just today 4 people were killed in Paris by gendarmes, the details are unclear. I was at a film screening last night where speakers from the MIB (ministre de l'immigration et banlieues - a political group set up by the immigrants) was showing films. Several times french police have been let off the hook for Assassinating people (why? because they're immigrants). The riots have got a much more political and current element to them that you simply dismiss.
What is anti-democratic is that the immigrants in the banlieue - who have been granted temporary residency - in some cases when they were even BORN in France, are not given a say, and are threatened with deportation under double peine.
