No, Rongotai, it is you who miss the point.
The point is that airlines do not wish to make themselves safer if it will cost them money. They do not wish to make pilot's maximum duty hours any shorter and the chance of pilot fatigue consequently slimmer, if it will cost them money. They do not wish to check that all baggage on board belongs to a passenger on the flight if it will cost them money.
And up until now, they have had their way, whatever the problem, whoever has pointed it out to them.
And that situation is not healthy. Because when the overarching consideration of ALL possible factors is making money, and making more money, then people's lives are in danger.
