I suspect many of the French would like very much for the Jews to leave. They just don't want to be seen as wanting them to leave.
something else I'd love to see the numbers on is exactly what sort of people the French Jews are, vs the "North African Immigrants."
Which are actually the sort who contribute to both French society, as well as the "tax base?" Which group is made up of a greater number of scholars, doctors, teachers, etc? With the French, it's always best to "follow the money."
