Why should someone be denied the chance of some sleep on long haul simply because you refuse to shell out the relative pittance for extra legroom seating?
Pittance? Any form of premium cabins are more than a pittance. Why should I be forced to pay extra, I didn't choose to be 6'4. If nobody reclines their seat, nobody has a problem. Economy is never going to be comfortable, and nobody is ever going to get a good night's sleep, recline or not. But the difference between reclining and not reclining into us tall folk is the difference between slightly uncomfortable and completely unbearable. I can't put me knees in the overhead compartment.
And believe me, they're going to get less sleep with my knees crushed into their seat than they would if they chose not to be selfish in the first place.
