I think & this is only one way of looking at it any Govt institution that has a budget like Cebterlink would be looking at the costs V the chances of you being employed & what the job market is like out there in any one particular field. Seeing as aviation is going down the toilet & jobs are sporadic at best funding anyone with a low chance of gaining employment then paying taxes back from it would be very low.
In essence the cost for one person who 'might' get a job in aviation after the Govt payed out squillions for training etc as against that same outlay being put to better use perhaps getting dozens of unemployed back into the work force says it all.
