Well, I'm an optimist, I think that response counts as partial agreement at least.
I also have some other root causes of the problem to consider.
Could it be that the French Republic
itself is at fault?
Perhaps it is simply too rigid. People are either French... or nothing.
'Nothing' is so unthinkable to the French state that they don't even keep official stats on race or ethnic origin on the basis that everyone is French.
In this way they have been blind to problems for years. How could the government even tell that sections of their society were underperforming?
The secular French state may have been perfect for times in which it was designed for but does it/can it work in the 21st century?
