My father shared with me an experience he had once when he did a presentation for a gaming organization in Las Vegas. The management showed him the gambling floor of the casino. They pointed out that because of the low-trust environment, coupled with the high risk of theft, the gambling floor had four to five levels of management. Thus, they had people watching people watching people watching people. In a high-trust culture, however, one to two levels of management would likely have sufficed.
Completely disagreed though. In some situations highly prone to exploitation and various uncontrollable factors, closely guarding key elements of business should stand.
