Line workers have a better idea of whether their jobs make any kind of sense. Yes, they don't often have the executive view, but the executives frequently have no idea how the work gets done all the way down the chain; they have a huge amount of blindness as to the realities and limitations of things on the ground. Especially at large organizations, they're relying on summaries of summaries of summaries observed by line managers summarizing information. Tons of information is lost that way. This is why high-level strategy fails. Theoretical ideas hit reality and fall apart pretty quickly. Few executives are grounded enough to actually know how things work.
