I agree with you that's how it should be, but experience tells me that everyone is insecure and it's hardly correlated with position and job security.

People lower down the chain are insecure because they could legitimately be let go at any time for any reason.

People higher up the chain are insecure because any loss of face is debilitating. Especially having failings pointed out by someone "below" them.
