The system, so no one in particular, so it will never get better until individuals can be held accountable.

Its easy to say someone being personally responsible would fix the problem.. Really this just encourages further nefarious organizational behavior. I.e. hiring people into big titles who can't even understand their liability and railroading them into what an informal management actually wants as far as risk/cost trade offs which are then even higher toward risk as there is a scapegoat.

Policy makers make the policy that must be followed. Of course the engineers would take the brunt of blame, even though the engineering groups never make policy.
