Now profits are important too. Companies need money. That's how they pay their employees, do R&D, stuff like that. If they don't make money, employees will get fired, and they won't be able to develop new, better and potentially safer planes.Wow, I'd have a variety of responses to this remarkable post.
Obviously, safety regulations should allow for the profitable production of planes and they clearly do, the rest should be up to the plane manufacturer. Now, profits as such aren't what creates jobs as such. Rather it's the productive use of capital - a patent troll making a mint creates zero jobs for example. Now, if a particular form of investment doesn't create jobs one place, it should be able to create them elsewhere. Guaranteeing profits in one sector has many pernicious effects, often including a lack of job growth rather than the reverse.
Just as much, the profit/safety equation is more complex than "more profits, more safety spending" (to say the least). For example, if safety regulations can always be ignored for profits, plane manufacturers will build less safe planes over time.
Finally, a management which responds to not being able to produce a new, unsafe design by making their present line of planes unsafe by "lowering standard" should be looking at jail time.
