Boy,
I'm sorry but you are wrong. The intervention from the french authorities has nothing to do with protecting the french social security from tax evasion. It has all to do with killing the competition to make room for the new Air France low cost subsidiary.
Also did you know that a certain AF subsidiary, Cityjet, also employs crew under foreign contracts, but strangely the french authorities don't seem to be interested to the point of raiding the AF offices in CDG.
The french contributors (myself included) know all too well how things work in France, I think you should take their view a bit more seriously. One thing is for sure : the french authorities have been trying for a while to get rid of eJ, and what we have just seen is merely the escalation of the effort they are putting into it.
