Rather: Money > consequences. And so far, they've been right. How likely will old managers that have long left, but fully participated, be held accountable?
You may be right.. your comment reminded me of the formula from Fight Club. Maybe the airlines made that calculus, reasoning that, after all this time their planes were safe enough, and the chance of an accident were low. Even still, it was cheaper to settle lawsuits.
"A new car built by my company leaves somewhere traveling at 60 mph. The rear differential locks up. The car crashes and burns with everyone trapped inside. Now, should we initiate a recall? Take the number of vehicles in the field, A, multiply by the probable rate of failure, B, multiply by the average out-of-court settlement, C. A times B times C equals X. If X is less than the cost of a recall, we don't do one."
