Guys “MPL stuffs”vs “experience” is beyond your scope of thoughts as a simple pilot.
It is much more a management matter and the key is:
1.You hire a very experienced pilot in your company who bring with him a specific skill that is valuable in the global market = >The pilot got the power and may cost you a lot if you want to keep him depending on your competitors capacity to provide better wages=> The pilot is independent and powerful.
OR
2.You spend a huge amount of $$ to train a smart guy who never flown differently something else than one of your specific aircraft like a robot applying the SOP you always taught to him= He owes you everything, he is not valuable in the global market then dependant, you got the power and full control. He is stuck, time goes on and the $$ come back.
The only reason Option 2 is not widely spread is because it depend on your fleet level of technology. The more Boeing, Airbus and others will make the pilot experience irrelevant by developing self-secured aircraft technologies, the more option 2 will be chosen by operators.
