Changes
The times they are a changing. If you employ and train them, you need to keep them for a while. The future will have lots of casual employment (not good for anyone), contracts, purchased training, multicrew pilot licences and bonding. Just like the RAAF and the airlines.
I forecast this a long time ago. The floods of wannabies have been excessive, and have undermined the career GA pilot (yes he DID exist, and will again) and all but destroyed conditions in GA. It's all been artificial. There never were that many jobs. So now the career GA pilot has gone overseas, or into another job, it is not so easy to find 1500 hour, or 3000 hour pilots. The professional bush pilot hardly exists anymore. and many of the wannabies have gone somewhere else to try to pay off their loans.
But of course we cannot expect the "highly educated" pilots to stay in GA though, can we?
