Are you saying higher prices would lead to better safety?
If so, I think it's optimistic to assume that would be the result, rather than just more profits.
I'm all for tighter regulations and enforcement on safety and maintenance, though.
Higher prices and regulations.
With no floor on pricing, there will always be enough greedy executives who are willing to cut corners to make money in a ruthlessly competitive environment, fully knowing that it is very hard to prosecute a C-level executive personally.
The other possible result will be that eventually the market "agrees upon" a minimum price floor while being in compliance to regulations - but that usually means that the company will be as bare-stripped of assets and reserves as possible, which means in turn that the slightest external shock can (and will) send not just one but multiple companies crashing down hard. We've seen this with Covid - an economy that has optimized itself for decades on running as lean as possible is very sensitive to all sorts of external interruptions. Of course, that's not directly relevant to safety... but indirectly it is, as the inevitable result of that is an oligo-, duo- or monopoly and then, we've seen with Boeing where that ends, incentives aligned too much to cut corners.
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.

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.
The industry (edit: planes in particular) is also decades more mature, as is manufacturing in general.
However, it's impossible to argue that deregulation made flying more dangerous, as the GP believes, simply because flying didn't become more dangerous. Sure, maybe we'd be even safer in the air if price deregulation hadn't happened, but that requires an impressive amount of handwaving. Overall, the tradeoff seems to have worked out incredibly well for everyone. The only people who are really in a position to object would be climate researchers.
A lot depends on your overall marketing. The airline can make money on a "stupid tax", e.g. people who didn't check twice the max. allowed weight of their baggage and have to pay a 100 USD/EUR fee for that single extra pound. I have seen it more than once.
People being people, you can almost rely on this happening frequently enough.
