Hotel Charlie, Yes I am sure about my opinion. I see it impossible to unions or individual members to make any change using old fashioned way, "with us or against".
In my opinion, the only chance is if the audience and governing authorities demand for change. The change might be achieved by affecting those people, customers and officials. When they feel loosing something, money for example, they could help steering the ship.
Unfortunately customers value low prices over pilots lifestyle and authorities are greatly affected by industry.
One should never give up, but one should also look for alternative paths instead. Good luck.
