I agree with your comments, it is a sad fact that because it has now become a common perception that 'you need an FI to get the hours to get a real job', it creates the mannerisms, which are noticed by the paying student, that there is no interest in the role. It is a stepping stone almost. That compounded with the limited experience of the new instructor increases the risk of dilution of the quality that could be produced. That student could then be one day, the individual who is conducting the pleasure flight, trial lesson your son/ daughter is on, or even your new co-pilot.
As Ascend Charlie states, a licence doesn't entitle you to a job, there is a massive responsibility on the training organisation to select at intervew the right candidates, and then provide that platform to give the level of service that is needed in producing quality aviation practioners?
