The difference is how measurable the consequences are. In aviation when there's a screw up people die right then and there. People dying is a very hard to game metric, and it provides a very strong incentive.

The consequences of bad management in a software project on the other hand are much more nebulous. And nobody died as a direct consequence of some manager being a jerk… oh wait, I'm sure some did (committed suicide or gone postal), but it's easy to just blame the worker instead of the working place.
