fcom you are wrong.
In many other cadet programs (other that ptf) the process is totally different:
1st_ selection
2nd_ cadet program
3rd_ passing all tests and exams
4th_ passing the TR
If you failed to meet the minimum requirements in steps 2,3, or 4...
Good Bye.
If you did OK...
5th_ hired with a permanent contract
The ptf programs that you advocate follow a different process. To begin with, there is no selection as such, other than money or is it?. Then, getting the licenses is very easy, nowadays, to be honest. Or isn't? Forrest Gump could do it in less than two years. The TRTOs involved rarely fail a pilot, or do they? And then you get (but this is not guaranteed) a temporary contract for 6 months, after which, next "candidates" will come, and you will have to pay your sims to remain current, etc..
You cannot compare!
In the proper cadet programs, cadets were the raw materials that airlines require to make the product: pilots.
In nowadays programs, cadets are the customers of a number of bloodsuckers, one of which are greedy airlines that want to magically turn costs into revenues.
The best pilots I know came through cadet programs. Very talented people. Very good training. Superb results.
