Trust fails in unequal, nonreciprocal power relations. [causal]
That we might not trust those who have power over us, especially when they have little reason to care for us individually, is no surprise. I depend heavily on your favor, while you depend not at all on mine. You can therefore do me substantial harm, while I can do you little or none. The mutual trust that depends on reciprocal relations cannot easily develop in such unequal, nonreciprocal contexts.
