"Not for profit", doesn't actually mean that they don't, or can't, make a profit. and true, they RFDS do pay more than their GA counterparts, and spend more on training, and uniforms etc.
IF the RFDS had to compete against GA companies run by "for profit" accountants, and using the cost factor they now have.... they wouldn't survive a month...!!!!!!!!!! they are a beauracracy hiding behind a legend. HOWEVER, they do do sterling work, and have my respect. I wish that I had been able to have a stint with them.
