I think greed is what's causing cut corners.
You mention Boeing, and they were quite healthily profitable during the entire time they were cutting corners on the 737 MAX. Airbus wasn't an existential threat. It still isn't, in fact, even after all the fallout.
> I'm all for tighter regulations and enforcement on safety and maintenance, though.
That's from my first comment in this thread. I'm not sure what part of my comments make you think you should ask me that question.
What I'm arguing is against the notion that having minimum prices would fix said greed.
