Indeed. Airlines do well, and they're heavily regulated. But they don't have armies of engineers doing nothing whilst court cases are worked out.

The flip side of that is monopoly. The only recent aviation accidents that have happened, have done so because, put bluntly, the FAA knows they didn't stand a chance if they blocked the only (US) big-jet maker from upgrading its planes. Were there (US) competitors, which once there were, they wouldn't blink at telling Boeing's transparently awful MAX design to go whistle.
