People are re enlisting, that should tell you something about the outside at the minute, so, unfortunately you guys are not in a particularly strong position to argue that there will be the "mass exodus" that never comes (mores the pity).
That said, as I've posted before, all my colleagues that have left are employed, save one, and that was not a real surprise, and ALL are enjoying a decent pay jump and/or an absolutely smashing work/life balance. As has been stated, worth a bloody fortune on its own!
