I think that attitude is part of the problem. If you're competent, it's usually much easier to find a new job than it is to take on entrenched cultural and funding problems that create risks. This further entrenches the problems by driving out dissenters, and if you work for a regulator, the 'creative destruction' of the free market can't fix it either.
While all true, by quitting you escalate the problem.
If upper layers "solve" it by hiring less competent people, then that is something on their conscience.
When the problem is at the top, just bearing with it at the bottom will not help at all. Even if you manage to save lives, you virtually sacrifice your own.
