here goes my dime....
Reduction of training cost by centralizing the facility will be countered by cost of travel and motels/hotels ( they'll look at the facts AFTER they get the bill), and training will inevitably get to expensive and brought back to the respective bases.
Then the scratchback starts to recuperate the lost money for this
"centralized facility ", and the pilots get a whack in their pay.
They then leave for more beneficial work and more "new" pilots need training.
Just my take on it, and I've been wrong many times before
