I think it's been accelerated by line captains refusing to take the responsibility of giving the cadets the training the system hasn't delivered.
It all sounds very idealistic Gnadenburg, and without doubt very well intentioned.
But let's take it to the extreme limit - let's not give the cadets any training at all beyond the absolute minimum regulatory requirements to be issued a licence, and let the line captains train them. Then we don't need all those extra trainers we can't get, and produces a 15% saving from the salary budget.
Job done.
