Percentages are important, my bum!
It's the amount of income these people have above and beyond an acceptable basic standard of living that's important. Another 15p here or there is an absolute nonsense.
It's easy to be blase about others incomes when you easily earn thousands of pounds over and above an acceptable basic wage.
And remember, it's these 'unskilled' people, including your dispatchers, pax agents and load controllers, who ensure your aircraft is safely loaded and fit to fly - all while you use your considerable skills to sit on your bum drinking coffee on the flight deck.
