I describe this phenomenon like cancer, and I described, when I was introducing this topic, how wrongdoers get away with things. They get promoted. They get more.... These are people who are, typically, both incompetent and dishonest, and they are totally focused on their own careers and self-interests.
If you can take those people out of the system, that sends a huge signal, and that's what's not happening in places like Transport Canada, where you have incompetent managers being promoted and disasters happening and no consequences for them. It's the same with Phoenix. There are no consequences for the people who created and designed this disaster, and there are no consequences in terms of understanding today what actually happened.
