And the other is that a lot of the decisions that bring up anti-MBA shitstorms and flamewars make it more than obvious that ethics were not much of a part of the MBA program the offenders attended.
The most obvious example of ethics getting railroaded was Boeing, and look where it got them to.
Look at the Boeing MCAS and VW emissions scandals. Individual engineers and test pilots were named and faced repercussions. The MBAs that sustained the environment where this poor decision making happened? Aside from the very senior executives, we have no clue who they are. They were able to stay in role or slink off to another opportunity. They might not even think they had any culpability.
* Enron
* General Electric and the lord and savior of MBAs, Jack Welch
* Valeant Pharmaceuticals
* Sears
* IBM
* McDonnell-Douglas (and later Boeing)
* Intel
* Stock buybacks in the airline and retail industries
