>I've never seen an organization take the actual proper steps (fire mid-management and PMs) to prevent the same thing from happening again.

One time, in my entire career have I seen this done, and it is as successful as you imagine it to be. Lots of weird problems coming out from having done it, but those are being treated as "Wow we are so glad we know about this problem" rather than "I hope those idiots come back to keep pulling the wool over my eyes".
