There's no issue with airline cadets.
The original poster is a GA operator, who is understandably concerned about the breakdown of the conventional career progression path from GA to the airlines, in favour of cadet programs.
His concern in this is not the welfare of the airlines, or the safety of the travelling public once there's no more pilots with "GA experience"
driving the 'buses and Boeings.
It's the clear and obvious fact that given the current state of GA, very few people in their right mind will touch it with a 40 foot pole, or even commence flight training outside of a cadet program, once the airlines become a closed shop and GA becomes a dead end career with no progression path.
Should this situation come to pass, it will obviously have a drastic impact on his ability to cherry pick one or two guys from the several hundred CV's he's used to having on his table.
Hence why he's a bit grumpy and crying that this is probably his "last post" and prophesizing that the whole industry is about to come to an end.
There's an obvious solution to this problem, but it would unfortunately involve the dreaded "spending of money"
