To be fair to Langewische, he is a decent writer and does actually know something about aviation, unlike most people who write about it. However he does seem to have taken a serious overdose of Boeing Kool-Aid here.
In fact, even if he were right that all right-thinking 'murcan pilots would have flown their way out of this (and there are certainly plenty of those who believe that) - it's STILL irresponsible (at best) to build an aircraft that can't be flown by 75% of the pilots who will get to do so. Suppose Toyota or Ford built a car that had 10x the fatal accidents of other cars, and their defence was "but the drivers just needed better training, it's terrible how under-qualified today's drivers are". I don't think that would go down very well. Maybe in 1960 it would have (the Renault Floride c. 1960 was indeed pretty much undrivable by normal mortals).
