To be precise, i feel that power itself is not coercive, but the use of power to create coercion is a form of corruption of power and causes further corruption. The corruption is seeded earlier in the process than the coercion itself, in that the coercion is created from thoughts within the actor and those thoughts are lacking in the needed heart balance for the power to be used in a balanced and non coercive way.

A simple, catchy, way to say this is probably 'Power Over Is Corruption'.
