Think it comes down to incentive structures and what kind of behavior is rewarded. In a well functioning company people creating value bottom up see an upward trajectory in their careers. Companies that lose their way end up in a limbo state where power brokers, star communicators, coordinators end up capturing all the value and the act of creating bottom up value becomes an irrational act. An employee will do exceptional work if they have some kind of belief that they will be able to monetize it by capturing some of the value created. Once this belief evaporates doing great work becomes a fools errand. We (humans) appear to be hard wired to reverse engineer the incentive structures both explicit and implicit in any given situation.
