Did you know that in the airline industry, they literally have a cost-benefit they do that they keep quiet about? In other words, they look at the profits they make by taking certain safety shortcuts, the likelihood of a bad accident and the payouts that might be required and cynically factor that as a "cost of doing business". If the cost is too high, then they're more likely to do things properly. It's all about profit, nothing else, the millions of people they transport are just the pawns needed to make that profit, nothing more than cattle.
I believe this happens in all the safety critical industries like cars, construction of all kinds, hospitals / healthcare, food production etc.
