I agree with you that some blame must be apportioned to management. But also I feel it's too easy as a developer to see yourself as part of a team and thus absolved of any individual blame. You're subsumed in the "team" - and ultimately no-one takes responsibly.

Even with management at fault, one cannot deny that the developers produced absolute garbage.

I hope the developers who worked on this system, no matter how much they feel they are not responsible for the failure of this project, will reflect on how the impact of software they built had devastating consequences on people's lives.
