We're lucky ASA pays us at all. And seriously that is a very veeeerry good wage just for training. Any other similar job in the world you'd have to pay to train and then not necessarily be guaranteed a job. It's not like you make the company any money while in training, where as the trainee blippees are straight-away doing their actual job, not just pretending like the atc trainees. Plus, what other job would you get paid that much as a trainee, then if you're a successful employee your pay doubles within a year & 1/2.
Trainee Network Controller with QR National is a somewhat similar job that offers all those factors.
