Here's the cloud/bubble/crystal tower I've been living in for the last years: France, Belgium, USA (only to mention those) and...oh I've been in Sweden too! Well never lived there long enough to talk about race troubles, social unrest or sharia kaliphate but have friends who have lived there all their lives, they never mentioned those either (I don't say problems don't exist though!). So how about you? In which cloud/bubble/crystal tower you've been in? Have you noted that I suggested you go see by yourself rather than watch on TV? I don't only watch, read or listen to news I also make news and also go to places. That is why I'm taking some time here to discuss with you because you seem somehow misinformed to me!
Why would unemployment in the US be due to "economic troubles and poor domestic policy" and not in other countries? Havent' they all faced the financial/economic crisis?
I've studied French Constitutional Law (amongst other), I read most of the Constitution (though I don't remember everything)! You're right when you say "Socialism is enshrined in the French constitution as is the right to work" but whatever other interpretation you have of this, is wrong. The problem lies in the job market rigidity and that has nothing to to with the Constitution but with the French labor code.
The British economy is falling back into recession and that's not because of the 400,000 French who work and live there but all the austerity measures/government policies etc etc I think nowadays you're free to move, go live, study & work wherever you think's best for your interest. There are few Brits who live and work in France as there are in Australia, USA, Canada etc etc
I must admit that "part" of your reasons for the European situation is right! But saying it's all due to socialism will be wrong! Well UK (not socialist that I know) is facing recession, France not but Spain yes! So bottom line is there is no perfect system (otherwise everyone would have adopted it long ago). Socialism has its defects just like capitalism. Similarly it's not because it works for the neighbors that it will necessarily work for you!
As for the presidential in France I'm well and fully aware of the situation but I'm not sure to have understood the reasoning behind your question! What did you mean?
