I kiiinda see where you're coming from but I guess I just don't buy it, TBH.
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.
Edit: I actually think I just don't get the gist of your question/comment.
> 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.
Okay, what possible fix for everpresent greed in US business management is there other than regulation and enforcement?
