OTOH, part of the reason the duopoly persists is because of heavy regulation, and specifically the strict safety regimen. From that angle Boeing has significant economic motivation to promote costly safety margins, particularly those which raise barriers to entry into their markets.
I understand the argument that Boeing employs countless conscientious, professional engineers. But in 2018, with American business culture having internalized decades of cynical, anti-social business practices, I'd be careful about overestimating the influence of the professional class.
