Pilots get paid not because they fly passengers or boxes, they get paid because their skills generate revenue for the company. It just so happens that boxes generate more revenue than people do. Your logic fails when you consider that charter outfits that flew people prior to 9/11 didn't make the same as dal or ual. Aren't the people valuable on all those planes too? When the pax carriers start charging more for their product so a plane full of pax generates the revenue of a plane full of boxes, then you might have a reason for the pax guys to ask for more money.
