This is indicative of something much larger taking place everywhere on the globe, because of decades upon decades of jobs' destructions, stagnating incomes, increased inequalities, and, above all, a total mistrust of the political "elite" that has proved to be a weak, malleable, corruptible and oblivious-to-the-common-man's issues' machine. I blame the liberals, partly, especially the media (Hollywood, magazines, commentators, TV hosts and other forums) for glossing over those real problems in favour of more societal things that only affect a fringe of the population, and which should have taken a backseat to social problems.
France is living the same ordeal, and there is no doubt in my mind that the extreme right is going to win the next elections. For years and years, the French media-machine turned a blind eye to the agonizing situations of famers and rural people; ridiculed those millions who dared to speak up against the irrational immigration policy...now, who's laughing?
The left is a joke. It renounced its ideals for cosmetics and trivial issues. It is paying the price dearly and, honestly, it deserves it.
