Sadly it doesn't come down to skill levels or ability to fly. It comes down to the bottom line of some faceless pencil pushing (read Excel bashing) accountant who can entice people to pay for a Type Rating or, even better, Line Training with a scant whiff of the promise of a job at the end of it.
Once there the whiff disappears into the morning mist and the next paying TR applicant sits in the still warm seat.
With the current state of affairs, coupled with FTO's seeming to continue to see the fabled 'pilot shortage' on the horizon and have the ability to sell that better than an East London car salesman in a sheepskin coat can sell a knackered car, there will always be applicants. They feel that paying will give them the 'edge'. Who can tell, maybe in a few years time it will.
This won't change. The airlines have got hold of the bone and it will take a lot to let them drop it. Airline flying is not the most demanding of flying. In fact, after many years flying various types, I have to say it can be downright dull. It does however, in the correct airline, pay the bills well. That will be enticement enough for lots of applicants.
