Competition
Prevailing wage stops the race to the bottom, If a CEO wants to be a better competator they can't cut wages as they are set by the board and all airlines pay the same. He must cut other variables in the profitababilty matrix, we will let him figure that out! Thats his/her job.
It's not a new idea, U.S. Grant signed the first Prevailing wage law in 1868! My wonder is why the Aviation Unions have not embraced the idea. The current pay situation is not good for anyone.
