You have to look at who does the hiring and who benefits from the churn: The managers themselves. Keeping old timers, they will take charge and be harder to manage. Each newcomer, will be at your mercy, to be formed and taken hostage for many years. Besides, an influx of chaos is good for grabbing more power. As it's really someone else's problem after all: Win win. So such situations are because someone benefits from the situation, even though the organization bleeds. Look at incentive structures and follow the money. Though even if unintentional, it follows from simple cause and effects.
