EuroATC,
Take it easy, don't get hyped up mate.
I know that it can be a hard life in the Romandie as a non-"Welsch". Especially GVA TWR/APP is well known for axing swiss germans. They don't stand a chance (at least it used to be like that, maybe it has changed by now).
Admittedly, the difference in tax is probably not as big, if you're on a B permit, since you get taxed on the source.
With a C permit (I believe) and for a local, the difference is definitely considerable.
Concerning being "in the position to make such comments" check your PM's.
