France has near 25% unemployment of youth. Some are worst like Italy and Spain. France also has a lot of islamic immigrants I think leading to some possibly leaving France to Syria to train, then coming home to cause these attacks.
Unemployed men in a sad state of mind with no gf/wife (useless men, who wants them?) leads to violence, radicalization, crime, you name it.
I actually fear America would/could be ending up like this considering how tough the job market is nowadays for a lot of people…even with degrees…
In a global economy, most jobs are now viewed as an unnecessary cost center and in a race to the bottom, (all the retailers did poor just lately) and Amazon killing everyone with little retail profits (those come from AWS), I wouldn’t be at all surprised if there were more violence in 20-30 years. Maybe even 10 if things were bad enough.
The whole situation in the middle east has been going on for thousands of years…I don’t think anyone is going to be solving it anytime soon.
