It's like a dark-mirror version of a really good principle in leadership philosophy, which was outlined in Starship Troopers by Robert Heinlein. "Everything that happens under your command is your responsibility." If a man fails to do his job in the correct way, it's because you failed to make a system that would train him properly, and possibly because you allowed the wrong man to be hired. Technically, every success is also your responsibility, but a smart leader spreads blame for success and privatizes blame for failure. In reality many leaders pretty much do the opposite.
