Les Misérables explains why so few immigrants to France find jobs:
Alas, the obvious, probably easiest, solution is taboo. Absent a major overhaul, Europe’s welfare state continues to make it difficult for low-skill, low-wage laborers to find work. In a system like France’s that protects the people already in jobs and keeps unemployment stuck at 10% (nearly triple that for the young), it’s little wonder that the banlieues are burning. No better way exists to make someone feel part of a society than to give him a job in it.
