Depone, fair point!
Just the number you've mentioned are in the high range, in my experience.
5000 net pcm, is not that far from reality in some bases. 7000 pcm for FO, whilst true, doesn't happen often and certainly not for the normal 2+ year FO who is paid back 200-300 euro, tops, in expenses each month. Rest is taxed.
The reality is the FR is a great place for some people, a nightmare for others
Sums it up well, in words w/o the numbers
