Conclusion: Business leaders make lousy engineers. They refuse to defer to others. They can't resist enforcing their judgment even in situations where their expertise is lacking. And never mind the fact that business concerns often conflict with safety which calls their judgment into question. This is essentially what happened with the Boeing 737 Max and it is what happened here too. In both cases, repeated warnings were ignored, overruled and dismissed by business leaders with minimal engineering experience and people died --- as a result of arrogance. Safety is only "pure waste" when your main focus is sales and marketing and your judgment is compromised.
