Senator McCain is a war hero - and you're not! So quit the holier-than-thou attitude.
McCain also makes two VALID points. Airline pilots working for US majors have too much leverage - without pilots you can't fly... The same is true about the flight attendants and the mechanics - this business is entirely too dependent upon labor to operate. The airline business is a $hit "business" to work in from a management perspective - very difficult to follow your fiduciary duty and maximize profits for shareholders.
McCain is also right that a major disruption/strike at this point in this weak economy could have an adverse affect on the system. Do you disagree with that? Are you an idiot? He's right about these two points - it's just that he doesn't convey them in a manner that suits you because you are too close to the issue - if someone threatens your livelihood you will fight back.
I agree that airline pilots deserve more money and that they are "underappreciated" by most people. But you people need to examine the opposite perspective - otherwise you risk sounding like an idiot. McCain also isn't afraid to say what he believes - you need to credit someone for that - even if it is a bit misguided...
I don't agree with every point McCain makes, but don't knock a war hero - he endured more PAIN than you would in most lifetimes. You may disagree with his stance, but don't knock him - you'll end up looking like a jerk!
